Python Elasticsearch Client¶

Official low-level client for Elasticsearch. Its goal is to provide common ground for all Elasticsearch-related code in Python; because of this it tries to be opinion-free and very extendable.

Installation¶

Install the elasticsearch package with pip:

$ python -m pip install elasticsearch

If your application uses async/await in Python you can install with the async extra:

$ python -m pip install elasticsearch[async]

Read more about how to use asyncio with this project.

Compatibility¶

The library is compatible with all Elasticsearch versions since 0.90.x but you have to use a matching major version:

For Elasticsearch 7.0 and later, use the major version 7 (7.x.y) of the library.

For Elasticsearch 6.0 and later, use the major version 6 (6.x.y) of the library.

For Elasticsearch 5.0 and later, use the major version 5 (5.x.y) of the library.

For Elasticsearch 2.0 and later, use the major version 2 (2.x.y) of the library, and so on.

The recommended way to set your requirements in your setup.py or requirements.txt is:

# Elasticsearch 7.x
elasticsearch>=7.0.0,<8.0.0

# Elasticsearch 6.x
elasticsearch>=6.0.0,<7.0.0

# Elasticsearch 5.x
elasticsearch>=5.0.0,<6.0.0

# Elasticsearch 2.x
elasticsearch>=2.0.0,<3.0.0

If you have a need to have multiple versions installed at the same time older versions are also released as elasticsearch2, elasticsearch5 and elasticsearch6.

Example Usage¶

from datetime import datetime
from elasticsearch import Elasticsearch
es = Elasticsearch()

doc = {
    'author': 'kimchy',
    'text': 'Elasticsearch: cool. bonsai cool.',
    'timestamp': datetime.now(),
}
res = es.index(index="test-index", id=1, body=doc)
print(res['result'])

res = es.get(index="test-index", id=1)
print(res['_source'])

es.indices.refresh(index="test-index")

res = es.search(index="test-index", body={"query": {"match_all": {}}})
print("Got %d Hits:" % res['hits']['total']['value'])
for hit in res['hits']['hits']:
    print("%(timestamp)s %(author)s: %(text)s" % hit["_source"])

Features¶

This client was designed as very thin wrapper around Elasticsearch’s REST API to allow for maximum flexibility. This means that there are no opinions in this client; it also means that some of the APIs are a little cumbersome to use from Python. We have created some Helpers to help with this issue as well as a more high level library (elasticsearch-dsl) on top of this one to provide a more convenient way of working with Elasticsearch.

Persistent Connections¶

elasticsearch-py uses persistent connections inside of individual connection pools (one per each configured or sniffed node). Out of the box you can choose between two http protocol implementations. See Transport classes for more information.

The transport layer will create an instance of the selected connection class per node and keep track of the health of individual nodes - if a node becomes unresponsive (throwing exceptions while connecting to it) it’s put on a timeout by the ConnectionPool class and only returned to the circulation after the timeout is over (or when no live nodes are left). By default nodes are randomized before being passed into the pool and round-robin strategy is used for load balancing.

You can customize this behavior by passing parameters to the Connection Layer API (all keyword arguments to the Elasticsearch class will be passed through). If what you want to accomplish is not supported you should be able to create a subclass of the relevant component and pass it in as a parameter to be used instead of the default implementation.

Automatic Retries¶

If a connection to a node fails due to connection issues (raises ConnectionError) it is considered in faulty state. It will be placed on hold for dead_timeout seconds and the request will be retried on another node. If a connection fails multiple times in a row the timeout will get progressively larger to avoid hitting a node that’s, by all indication, down. If no live connection is available, the connection that has the smallest timeout will be used.

By default retries are not triggered by a timeout (ConnectionTimeout), set retry_on_timeout to True to also retry on timeouts.

Sniffing¶

The client can be configured to inspect the cluster state to get a list of nodes upon startup, periodically and/or on failure. See Transport parameters for details.

Some example configurations:

from elasticsearch import Elasticsearch

# by default we don't sniff, ever
es = Elasticsearch()

# you can specify to sniff on startup to inspect the cluster and load
# balance across all nodes
es = Elasticsearch(["seed1", "seed2"], sniff_on_start=True)

# you can also sniff periodically and/or after failure:
es = Elasticsearch(["seed1", "seed2"],
          sniff_on_start=True,
          sniff_on_connection_fail=True,
          sniffer_timeout=60)

Thread safety¶

The client is thread safe and can be used in a multi threaded environment. Best practice is to create a single global instance of the client and use it throughout your application. If your application is long-running consider turning on Sniffing to make sure the client is up to date on the cluster location.

By default we allow urllib3 to open up to 10 connections to each node, if your application calls for more parallelism, use the maxsize parameter to raise the limit:

# allow up to 25 connections to each node
es = Elasticsearch(["host1", "host2"], maxsize=25)

Note

Since we use persistent connections throughout the client it means that the client doesn’t tolerate fork very well. If your application calls for multiple processes make sure you create a fresh client after call to fork. Note that Python’s multiprocessing module uses fork to create new processes on POSIX systems.

SSL and Authentication¶

You can configure the client to use SSL for connecting to your elasticsearch cluster, including certificate verification and HTTP auth:

from elasticsearch import Elasticsearch

# you can use RFC-1738 to specify the url
es = Elasticsearch(['https://user:secret@localhost:443'])

# ... or specify common parameters as kwargs

es = Elasticsearch(
    ['localhost', 'otherhost'],
    http_auth=('user', 'secret'),
    scheme="https",
    port=443,
)

# SSL client authentication using client_cert and client_key

from ssl import create_default_context

context = create_default_context(cafile="path/to/cert.pem")
es = Elasticsearch(
    ['localhost', 'otherhost'],
    http_auth=('user', 'secret'),
    scheme="https",
    port=443,
    ssl_context=context,
)

Warning

elasticsearch-py doesn’t ship with default set of root certificates. To have working SSL certificate validation you need to either specify your own as cafile or capath or cadata or install certifi which will be picked up automatically.

See class Urllib3HttpConnection for detailed description of the options.

Connecting via Cloud ID¶

Cloud ID is an easy way to configure your client to work with your Elastic Cloud deployment. Combine the cloud_id with either http_auth or api_key to authenticate with your Elastic Cloud deployment.

Using cloud_id enables TLS verification and HTTP compression by default and sets the port to 443 unless otherwise overwritten via the port parameter or the port value encoded within cloud_id. Using Cloud ID also disables sniffing.

from elasticsearch import Elasticsearch

es = Elasticsearch(
    cloud_id="cluster-1:dXMa5Fx...",
    http_auth=("elastic", "<password>"),
)

API Key Authentication¶

You can configure the client to use Elasticsearch’s API Key for connecting to your cluster. Please note this authentication method has been introduced with release of Elasticsearch 6.7.0.

from elasticsearch import Elasticsearch

# you can use the api key tuple
es = Elasticsearch(
    ['node-1', 'node-2', 'node-3'],
    api_key=('id', 'api_key'),
)

# or you pass the base 64 encoded token
es = Elasticsearch(
    ['node-1', 'node-2', 'node-3'],
    api_key='base64encoded tuple',
)

Logging¶

elasticsearch-py uses the standard logging library from python to define two loggers: elasticsearch and elasticsearch.trace. elasticsearch is used by the client to log standard activity, depending on the log level. elasticsearch.trace can be used to log requests to the server in the form of curl commands using pretty-printed json that can then be executed from command line. Because it is designed to be shared (for example to demonstrate an issue) it also just uses localhost:9200 as the address instead of the actual address of the host. If the trace logger has not been configured already it is set to propagate=False so it needs to be activated separately.

Environment considerations¶

When using the client there are several limitations of your environment that could come into play.

When using an HTTP load balancer you cannot use the Sniffing functionality - the cluster would supply the client with IP addresses to directly connect to the cluster, circumventing the load balancer. Depending on your configuration this might be something you don’t want or break completely.

In some environments (notably on Google App Engine) your HTTP requests might be restricted so that GET requests won’t accept body. In that case use the send_get_body_as parameter of Transport to send all bodies via post:

from elasticsearch import Elasticsearch
es = Elasticsearch(send_get_body_as='POST')

Compression¶

When using capacity-constrained networks (low throughput), it may be handy to enable compression. This is especially useful when doing bulk loads or inserting large documents. This will configure compression.

from elasticsearch import Elasticsearch
es = Elasticsearch(hosts, http_compress=True)

Compression is enabled by default when connecting to Elastic Cloud via cloud_id.

Running on AWS with IAM¶

If you want to use this client with IAM based authentication on AWS you can use the requests-aws4auth package:

from elasticsearch import Elasticsearch, RequestsHttpConnection
from requests_aws4auth import AWS4Auth

host = 'YOURHOST.us-east-1.es.amazonaws.com'
awsauth = AWS4Auth(YOUR_ACCESS_KEY, YOUR_SECRET_KEY, REGION, 'es')

es = Elasticsearch(
    hosts=[{'host': host, 'port': 443}],
    http_auth=awsauth,
    use_ssl=True,
    verify_certs=True,
    connection_class=RequestsHttpConnection
)
print(es.info())

Customization¶

Custom serializers¶

By default, JSONSerializer is used to encode all outgoing requests. However, you can implement your own custom serializer:

from elasticsearch.serializer import JSONSerializer

class SetEncoder(JSONSerializer):
    def default(self, obj):
        if isinstance(obj, set):
            return list(obj)
        if isinstance(obj, Something):
            return 'CustomSomethingRepresentation'
        return JSONSerializer.default(self, obj)

es = Elasticsearch(serializer=SetEncoder())

Elasticsearch-DSL¶

For a more high level client library with more limited scope, have a look at elasticsearch-dsl - a more pythonic library sitting on top of elasticsearch-py.

elasticsearch-dsl provides a more convenient and idiomatic way to write and manipulate queries by mirroring the terminology and structure of Elasticsearch JSON DSL while exposing the whole range of the DSL from Python either directly using defined classes or a queryset-like expressions.

It also provides an optional persistence layer for working with documents as Python objects in an ORM-like fashion: defining mappings, retrieving and saving documents, wrapping the document data in user-defined classes.

Contents¶

API Documentation¶

All the API calls map the raw REST api as closely as possible, including the distinction between required and optional arguments to the calls. This means that the code makes distinction between positional and keyword arguments; we, however, recommend that people use keyword arguments for all calls for consistency and safety.

Note

for compatibility with the Python ecosystem we use from_ instead of from and doc_type instead of type as parameter names.

Global options¶

Some parameters are added by the client itself and can be used in all API calls.

Ignore¶

An API call is considered successful (and will return a response) if elasticsearch returns a 2XX response. Otherwise an instance of TransportError (or a more specific subclass) will be raised. You can see other exception and error states in Exceptions. If you do not wish an exception to be raised you can always pass in an ignore parameter with either a single status code that should be ignored or a list of them:

from elasticsearch import Elasticsearch
es = Elasticsearch()

# ignore 400 cause by IndexAlreadyExistsException when creating an index
es.indices.create(index='test-index', ignore=400)

# ignore 404 and 400
es.indices.delete(index='test-index', ignore=[400, 404])

Timeout¶

Global timeout can be set when constructing the client (see Connection’s timeout parameter) or on a per-request basis using request_timeout (float value in seconds) as part of any API call, this value will get passed to the perform_request method of the connection class:

# only wait for 1 second, regardless of the client's default
es.cluster.health(wait_for_status='yellow', request_timeout=1)

Note

Some API calls also accept a timeout parameter that is passed to Elasticsearch server. This timeout is internal and doesn’t guarantee that the request will end in the specified time.

Tracking Requests with Opaque ID¶

You can enrich your requests against Elasticsearch with an identifier string, that allows you to discover this identifier in deprecation logs, to support you with identifying search slow log origin or to help with identifying running tasks.

from elasticsearch import Elasticsearch

client = Elasticsearch()

# You can apply X-Opaque-Id in any API request via 'opaque_id':
resp = client.get(index="test", id="1", opaque_id="request-1")

Response Filtering¶

The filter_path parameter is used to reduce the response returned by elasticsearch. For example, to only return _id and _type, do:

es.search(index='test-index', filter_path=['hits.hits._id', 'hits.hits._type'])

It also supports the * wildcard character to match any field or part of a field’s name:

es.search(index='test-index', filter_path=['hits.hits._*'])

Elasticsearch¶

class elasticsearch.Elasticsearch(hosts=None, transport_class=<class 'elasticsearch.transport.Transport'>, **kwargs)¶

Elasticsearch low-level client. Provides a straightforward mapping from Python to ES REST endpoints.

The instance has attributes cat, cluster, indices, ingest, nodes, snapshot and tasks that provide access to instances of CatClient, ClusterClient, IndicesClient, IngestClient, NodesClient, SnapshotClient and TasksClient respectively. This is the preferred (and only supported) way to get access to those classes and their methods.

You can specify your own connection class which should be used by providing the connection_class parameter:

# create connection to localhost using the ThriftConnection
es = Elasticsearch(connection_class=ThriftConnection)

If you want to turn on Sniffing you have several options (described in Transport):

# create connection that will automatically inspect the cluster to get
# the list of active nodes. Start with nodes running on 'esnode1' and
# 'esnode2'
es = Elasticsearch(
    ['esnode1', 'esnode2'],
    # sniff before doing anything
    sniff_on_start=True,
    # refresh nodes after a node fails to respond
    sniff_on_connection_fail=True,
    # and also every 60 seconds
    sniffer_timeout=60
)

Different hosts can have different parameters, use a dictionary per node to specify those:

# connect to localhost directly and another node using SSL on port 443
# and an url_prefix. Note that ``port`` needs to be an int.
es = Elasticsearch([
    {'host': 'localhost'},
    {'host': 'othernode', 'port': 443, 'url_prefix': 'es', 'use_ssl': True},
])

If using SSL, there are several parameters that control how we deal with certificates (see Urllib3HttpConnection for detailed description of the options):

es = Elasticsearch(
    ['localhost:443', 'other_host:443'],
    # turn on SSL
    use_ssl=True,
    # make sure we verify SSL certificates
    verify_certs=True,
    # provide a path to CA certs on disk
    ca_certs='/path/to/CA_certs'
)

If using SSL, but don’t verify the certs, a warning message is showed optionally (see Urllib3HttpConnection for detailed description of the options):

es = Elasticsearch(
    ['localhost:443', 'other_host:443'],
    # turn on SSL
    use_ssl=True,
    # no verify SSL certificates
    verify_certs=False,
    # don't show warnings about ssl certs verification
    ssl_show_warn=False
)

SSL client authentication is supported (see Urllib3HttpConnection for detailed description of the options):

es = Elasticsearch(
    ['localhost:443', 'other_host:443'],
    # turn on SSL
    use_ssl=True,
    # make sure we verify SSL certificates
    verify_certs=True,
    # provide a path to CA certs on disk
    ca_certs='/path/to/CA_certs',
    # PEM formatted SSL client certificate
    client_cert='/path/to/clientcert.pem',
    # PEM formatted SSL client key
    client_key='/path/to/clientkey.pem'
)

Alternatively you can use RFC-1738 formatted URLs, as long as they are not in conflict with other options:

es = Elasticsearch(
    [
        'http://user:secret@localhost:9200/',
        'https://user:secret@other_host:443/production'
    ],
    verify_certs=True
)

By default, JSONSerializer is used to encode all outgoing requests. However, you can implement your own custom serializer:

from elasticsearch.serializer import JSONSerializer

class SetEncoder(JSONSerializer):
    def default(self, obj):
        if isinstance(obj, set):
            return list(obj)
        if isinstance(obj, Something):
            return 'CustomSomethingRepresentation'
        return JSONSerializer.default(self, obj)

es = Elasticsearch(serializer=SetEncoder())

Parameters:

hosts – list of nodes, or a single node, we should connect to. Node should be a dictionary ({“host”: “localhost”, “port”: 9200}), the entire dictionary will be passed to the Connection class as kwargs, or a string in the format of host[:port] which will be translated to a dictionary automatically. If no value is given the Connection class defaults will be used.
transport_class – Transport subclass to use.
kwargs – any additional arguments will be passed on to the Transport class and, subsequently, to the Connection instances.

Using Asyncio with Elasticsearch¶

Starting in elasticsearch-py v7.8.0 for Python 3.6+ the elasticsearch package supports async/await with Asyncio and Aiohttp. You can either install aiohttp directly or use the [async] extra:

$ python -m pip install elasticsearch>=7.8.0 aiohttp

# - OR -

$ python -m pip install elasticsearch[async]>=7.8.0
Note

Async functionality is a new feature of this library in v7.8.0+ so please open an issue if you find an issue or have a question about async support.

Getting Started with Async¶

After installation all async API endpoints are available via AsyncElasticsearch and are used in the same way as other APIs, just with an extra await:

import asyncio
from elasticsearch import AsyncElasticsearch

es = AsyncElasticsearch()

async def main():
    resp = await es.search(
        index="documents",
        body={"query": {"match_all": {}}}
        size=20,
    )
    print(resp)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

All APIs that are available under the sync client are also available under the async client.

ASGI Applications and Elastic APM¶

ASGI (Asynchronous Server Gateway Interface) is a new way to serve Python web applications making use of async I/O to achieve better performance. Some examples of ASGI frameworks include FastAPI, Django 3.0+, and Starlette. If you’re using one of these frameworks along with Elasticsearch then you should be using AsyncElasticsearch to avoid blocking the event loop with synchronous network calls for optimal performance.

Elastic APM also supports tracing of async Elasticsearch queries just the same as synchronous queries. For an example on how to configure AsyncElasticsearch with a popular ASGI framework FastAPI and APM tracing there is a pre-built example in the examples/fastapi-apm directory.

Frequently Asked Questions¶

NameError / ImportError when importing `AsyncElasticsearch`?¶

If when trying to use AsyncElasticsearch and you’re receiving a NameError or ImportError you should ensure that you’re running Python 3.6+ (check with $ python --version) and that you have aiohttp installed in your environment (check with $ python -m pip freeze | grep aiohttp). If either of the above conditions is not met then async support won’t be available.

What about the `elasticsearch-async` package?¶

Previously asyncio was supported separately via the elasticsearch-async package. The elasticsearch-async package has been deprecated in favor of AsyncElasticsearch provided by the elasticsearch package in v7.8 and onwards.

Receiving ‘Unclosed client session / connector’ warning?¶

This warning is created by aiohttp when an open HTTP connection is garbage collected. You’ll typically run into this when closing your application. To resolve the issue ensure that close() is called before the AsyncElasticsearch instance is garbage collected.

For example if using FastAPI that might look like this:

from fastapi import FastAPI
from elasticsearch import AsyncElasticsearch

app = FastAPI()
es = AsyncElasticsearch()

# This gets called once the app is shutting down.
@app.on_event("shutdown")
async def app_shutdown():
    await es.close()

Async Helpers¶

Async variants of all helpers are available in elasticsearch.helpers and are all prefixed with async_*. You’ll notice that these APIs are identical to the ones in the sync Helpers documentation.

All async helpers that accept an iterator or generator also accept async iterators and async generators.

Bulk and Streaming Bulk¶

elasticsearch.helpers.async_bulk(client, actions, stats_only=False, *args, **kwargs)¶

Helper for the bulk() api that provides a more human friendly interface - it consumes an iterator of actions and sends them to elasticsearch in chunks. It returns a tuple with summary information - number of successfully executed actions and either list of errors or number of errors if stats_only is set to True. Note that by default we raise a BulkIndexError when we encounter an error so options like stats_only only+ apply when raise_on_error is set to False.

When errors are being collected original document data is included in the error dictionary which can lead to an extra high memory usage. If you need to process a lot of data and want to ignore/collect errors please consider using the async_streaming_bulk() helper which will just return the errors and not store them in memory.

Parameters:

client – instance of AsyncElasticsearch to use

actions – iterator containing the actions

stats_only – if True only report number of successful/failed operations instead of just number of successful and a list of error responses

Any additional keyword arguments will be passed to async_streaming_bulk() which is used to execute the operation, see async_streaming_bulk() for more accepted parameters.
import asyncio
from elasticsearch import AsyncElasticsearch
from elasticsearch.helpers import async_bulk

es = AsyncElasticsearch()

async def gendata():
    mywords = ['foo', 'bar', 'baz']
    for word in mywords:
        yield {
            "_index": "mywords",
            "doc": {"word": word},
        }

async def main():
    await async_bulk(es, gendata())

loop = asyncio.get_event_loop()
loop.run_until_complete(main())
elasticsearch.helpers.async_streaming_bulk(client, actions, chunk_size=500, max_chunk_bytes=104857600, raise_on_error=True, expand_action_callback=<function expand_action>, raise_on_exception=True, max_retries=0, initial_backoff=2, max_backoff=600, yield_ok=True, *args, **kwargs)¶

Streaming bulk consumes actions from the iterable passed in and yields results per action. For non-streaming usecases use async_bulk() which is a wrapper around streaming bulk that returns summary information about the bulk operation once the entire input is consumed and sent.

If you specify max_retries it will also retry any documents that were rejected with a 429 status code. To do this it will wait (by calling asyncio.sleep) for initial_backoff seconds and then, every subsequent rejection for the same chunk, for double the time every time up to max_backoff seconds.

Parameters:

client – instance of AsyncElasticsearch to use

actions – iterable or async iterable containing the actions to be executed

chunk_size – number of docs in one chunk sent to es (default: 500)

max_chunk_bytes – the maximum size of the request in bytes (default: 100MB)

raise_on_error – raise BulkIndexError containing errors (as .errors) from the execution of the last chunk when some occur. By default we raise.

raise_on_exception – if False then don’t propagate exceptions from call to bulk and just report the items that failed as failed.

expand_action_callback – callback executed on each action passed in, should return a tuple containing the action line and the data line (None if data line should be omitted).

Scan¶

elasticsearch.helpers.async_scan(client, query=None, scroll='5m', raise_on_error=True, preserve_order=False, size=1000, request_timeout=None, clear_scroll=True, scroll_kwargs=None, **kwargs)¶
Simple abstraction on top of the scroll() api - a simple iterator that yields all hits as returned by underlining scroll requests.

By default scan does not return results in any pre-determined order. To have a standard order in the returned documents (either by score or explicit sort definition) when scrolling, use preserve_order=True. This may be an expensive operation and will negate the performance benefits of using scan.

Parameters:

client – instance of AsyncElasticsearch to use

query – body for the search() api

scroll – Specify how long a consistent view of the index should be maintained for scrolled search

raise_on_error – raises an exception (ScanError) if an error is encountered (some shards fail to execute). By default we raise.

preserve_order – don’t set the search_type to scan - this will cause the scroll to paginate with preserving the order. Note that this can be an extremely expensive operation and can easily lead to unpredictable results, use with caution.

size – size (per shard) of the batch send at each iteration.

request_timeout – explicit timeout for each call to scan

clear_scroll – explicitly calls delete on the scroll id via the clear scroll API at the end of the method on completion or error, defaults to true.

scroll_kwargs – additional kwargs to be passed to scroll()

Any additional keyword arguments will be passed to the initial search() call:
async_scan(es,
    query={"query": {"match": {"title": "python"}}},
    index="orders-*",
    doc_type="books"
)
import asyncio
from elasticsearch import AsyncElasticsearch
from elasticsearch.helpers import async_scan

es = AsyncElasticsearch()

async def main():
    async for doc in async_scan(
        client=es,
        query={"query": {"match": {"title": "python"}}},
        index="orders-*"
    ):
        print(doc)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

Reindex¶

elasticsearch.helpers.async_reindex(client, source_index, target_index, query=None, target_client=None, chunk_size=500, scroll='5m', scan_kwargs={}, bulk_kwargs={})¶

Reindex all documents from one index that satisfy a given query to another, potentially (if target_client is specified) on a different cluster. If you don’t specify the query you will reindex all the documents.

Since 2.3 a reindex() api is available as part of elasticsearch itself. It is recommended to use the api instead of this helper wherever possible. The helper is here mostly for backwards compatibility and for situations where more flexibility is needed.

Note

This helper doesn’t transfer mappings, just the data.

Parameters:

client – instance of AsyncElasticsearch to use (for read if target_client is specified as well)

source_index – index (or list of indices) to read documents from

target_index – name of the index in the target cluster to populate

query – body for the search() api

target_client – optional, is specified will be used for writing (thus enabling reindex between clusters)

chunk_size – number of docs in one chunk sent to es (default: 500)

scroll – Specify how long a consistent view of the index should be maintained for scrolled search

scan_kwargs – additional kwargs to be passed to async_scan()

bulk_kwargs – additional kwargs to be passed to async_bulk()

API Reference¶

The API of AsyncElasticsearch is nearly identical to the API of Elasticsearch with the exception that every API call like search() is an async function and requires an await to properly return the response body.

AsyncElasticsearch¶

Note

To reference Elasticsearch APIs that are namespaced like .indices.create() refer to the sync API reference. These APIs are identical between sync and async.
class elasticsearch.AsyncElasticsearch(hosts=None, transport_class=<class 'elasticsearch._async.transport.AsyncTransport'>, **kwargs)¶
Elasticsearch low-level client. Provides a straightforward mapping from Python to ES REST endpoints.

The instance has attributes cat, cluster, indices, ingest, nodes, snapshot and tasks that provide access to instances of CatClient, ClusterClient, IndicesClient, IngestClient, NodesClient, SnapshotClient and TasksClient respectively. This is the preferred (and only supported) way to get access to those classes and their methods.

You can specify your own connection class which should be used by providing the connection_class parameter:
# create connection to localhost using the ThriftConnection
es = Elasticsearch(connection_class=ThriftConnection)
If you want to turn on Sniffing you have several options (described in Transport):
# create connection that will automatically inspect the cluster to get
# the list of active nodes. Start with nodes running on 'esnode1' and
# 'esnode2'
es = Elasticsearch(
    ['esnode1', 'esnode2'],
    # sniff before doing anything
    sniff_on_start=True,
    # refresh nodes after a node fails to respond
    sniff_on_connection_fail=True,
    # and also every 60 seconds
    sniffer_timeout=60
)
Different hosts can have different parameters, use a dictionary per node to specify those:
# connect to localhost directly and another node using SSL on port 443
# and an url_prefix. Note that ``port`` needs to be an int.
es = Elasticsearch([
    {'host': 'localhost'},
    {'host': 'othernode', 'port': 443, 'url_prefix': 'es', 'use_ssl': True},
])
If using SSL, there are several parameters that control how we deal with certificates (see Urllib3HttpConnection for detailed description of the options):
es = Elasticsearch(
    ['localhost:443', 'other_host:443'],
    # turn on SSL
    use_ssl=True,
    # make sure we verify SSL certificates
    verify_certs=True,
    # provide a path to CA certs on disk
    ca_certs='/path/to/CA_certs'
)
If using SSL, but don’t verify the certs, a warning message is showed optionally (see Urllib3HttpConnection for detailed description of the options):
es = Elasticsearch(
    ['localhost:443', 'other_host:443'],
    # turn on SSL
    use_ssl=True,
    # no verify SSL certificates
    verify_certs=False,
    # don't show warnings about ssl certs verification
    ssl_show_warn=False
)
SSL client authentication is supported (see Urllib3HttpConnection for detailed description of the options):
es = Elasticsearch(
    ['localhost:443', 'other_host:443'],
    # turn on SSL
    use_ssl=True,
    # make sure we verify SSL certificates
    verify_certs=True,
    # provide a path to CA certs on disk
    ca_certs='/path/to/CA_certs',
    # PEM formatted SSL client certificate
    client_cert='/path/to/clientcert.pem',
    # PEM formatted SSL client key
    client_key='/path/to/clientkey.pem'
)
Alternatively you can use RFC-1738 formatted URLs, as long as they are not in conflict with other options:
es = Elasticsearch(
    [
        'http://user:secret@localhost:9200/',
        'https://user:secret@other_host:443/production'
    ],
    verify_certs=True
)
By default, JSONSerializer is used to encode all outgoing requests. However, you can implement your own custom serializer:
from elasticsearch.serializer import JSONSerializer

class SetEncoder(JSONSerializer):
    def default(self, obj):
        if isinstance(obj, set):
            return list(obj)
        if isinstance(obj, Something):
            return 'CustomSomethingRepresentation'
        return JSONSerializer.default(self, obj)

es = Elasticsearch(serializer=SetEncoder())
Parameters:

hosts – list of nodes, or a single node, we should connect to. Node should be a dictionary ({“host”: “localhost”, “port”: 9200}), the entire dictionary will be passed to the Connection class as kwargs, or a string in the format of host[:port] which will be translated to a dictionary automatically. If no value is given the Connection class defaults will be used.

transport_class – Transport subclass to use.

kwargs – any additional arguments will be passed on to the Transport class and, subsequently, to the Connection instances.

headers – dictionary of headers, will be handed over to the underlying Connection class
params – dictionary of query parameters, will be handed over to the underlying Connection class for serialization
body – body of the request, will be serialized using serializer and passed to the connection

set_connections(hosts)¶

Instantiate all the connections and create new connection pool to hold them. Tries to identify unchanged hosts and re-use existing Connection instances.

Parameters:	hosts – same as __init__

sniff_hosts(initial=False)¶

Obtain a list of nodes from the cluster and create a new connection pool using the information retrieved.

To extract the node connection parameters use the nodes_to_host_callback.

Parameters:	initial – flag indicating if this is during startup (`sniff_on_start`), ignore the `sniff_timeout` if `True`

Connection Pool¶

class elasticsearch.ConnectionPool(connections, dead_timeout=60, selector_class=RoundRobinSelector, randomize_hosts=True, ** kwargs)¶

Container holding the Connection instances, managing the selection process (via a ConnectionSelector) and dead connections.

It’s only interactions are with the Transport class that drives all the actions within ConnectionPool.

Initially connections are stored on the class as a list and, along with the connection options, get passed to the ConnectionSelector instance for future reference.

Upon each request the Transport will ask for a Connection via the get_connection method. If the connection fails (it’s perform_request raises a ConnectionError) it will be marked as dead (via mark_dead) and put on a timeout (if it fails N times in a row the timeout is exponentially longer - the formula is default_timeout * 2 ** (fail_count - 1)). When the timeout is over the connection will be resurrected and returned to the live pool. A connection that has been previously marked as dead and succeeds will be marked as live (its fail count will be deleted).

Parameters:

connections – list of tuples containing the Connection instance and it’s options
dead_timeout – number of seconds a connection should be retired for after a failure, increases on consecutive failures
timeout_cutoff – number of consecutive failures after which the timeout doesn’t increase
selector_class – ConnectionSelector subclass to use if more than one connection is live
randomize_hosts – shuffle the list of connections upon arrival to avoid dog piling effect across processes

close()¶: Explicitly closes connections

get_connection()¶

Return a connection from the pool using the ConnectionSelector instance.

It tries to resurrect eligible connections, forces a resurrection when no connections are availible and passes the list of live connections to the selector instance to choose from.

Returns a connection instance and it’s current fail count.

mark_dead(connection, now=None)¶

Mark the connection as dead (failed). Remove it from the live pool and put it on a timeout.

Parameters:	connection – the failed instance

mark_live(connection)¶

Mark connection as healthy after a resurrection. Resets the fail counter for the connection.

Parameters:	connection – the connection to redeem

resurrect(force=False)¶

Attempt to resurrect a connection from the dead pool. It will try to locate one (not all) eligible (it’s timeout is over) connection to return to the live pool. Any resurrected connection is also returned.

Parameters:	force – resurrect a connection even if there is none eligible (used when we have no live connections). If force is specified resurrect always returns a connection.

Connection Selector¶

class elasticsearch.ConnectionSelector(opts)¶

Simple class used to select a connection from a list of currently live connection instances. In init time it is passed a dictionary containing all the connections’ options which it can then use during the selection process. When the select method is called it is given a list of currently live connections to choose from.

The options dictionary is the one that has been passed to Transport as hosts param and the same that is used to construct the Connection object itself. When the Connection was created from information retrieved from the cluster via the sniffing process it will be the dictionary returned by the host_info_callback.

Example of where this would be useful is a zone-aware selector that would only select connections from it’s own zones and only fall back to other connections where there would be none in it’s zones.

Parameters:	opts – dictionary of connection instances and their options

select(connections)¶

Select a connection from the given list.

Parameters:	connections – list of live connections to choose from

Urllib3HttpConnection (default connection_class)¶

If you have complex SSL logic for connecting to Elasticsearch using an SSLContext object might be more helpful. You can create one natively using the python SSL library with the create_default_context (https://docs.python.org/3/library/ssl.html#ssl.create_default_context) method.

To create an SSLContext object you only need to use one of cafile, capath or cadata:

>>> from ssl import create_default_context
>>> context = create_default_context(cafile=None, capath=None, cadata=None)

cafile is the path to your CA File
capath is the directory of a collection of CA’s
cadata is either an ASCII string of one or more PEM-encoded certificates or a bytes-like object of DER-encoded certificates.

Please note that the use of SSLContext is only available for Urllib3.

class elasticsearch.Urllib3HttpConnection(host='localhost', port=None, http_auth=None, use_ssl=False, verify_certs=<object object>, ssl_show_warn=<object object>, ca_certs=None, client_cert=None, client_key=None, ssl_version=None, ssl_assert_hostname=None, ssl_assert_fingerprint=None, maxsize=10, headers=None, ssl_context=None, http_compress=None, cloud_id=None, api_key=None, opaque_id=None, **kwargs)¶

close()¶: Explicitly closes connection

Transport classes¶

List of transport classes that can be used, simply import your choice and pass it to the constructor of Elasticsearch as connection_class. Note that the RequestsHttpConnection requires requests to be installed.

For example to use the requests-based connection just import it and use it:

from elasticsearch import Elasticsearch, RequestsHttpConnection
es = Elasticsearch(connection_class=RequestsHttpConnection)

The default connection class is based on urllib3 which is more performant and lightweight than the optional requests-based class. Only use RequestsHttpConnection if you have need of any of requests advanced features like custom auth plugins etc.

Helpers¶

Collection of simple helper functions that abstract some specifics of the raw API.

Bulk helpers¶

There are several helpers for the bulk API since its requirement for specific formatting and other considerations can make it cumbersome if used directly.

All bulk helpers accept an instance of Elasticsearch class and an iterable actions (any iterable, can also be a generator, which is ideal in most cases since it will allow you to index large datasets without the need of loading them into memory).

The items in the action iterable should be the documents we wish to index in several formats. The most common one is the same as returned by search(), for example:

{
    '_index': 'index-name',
    '_type': 'document',
    '_id': 42,
    '_routing': 5,
    'pipeline': 'my-ingest-pipeline',
    '_source': {
        "title": "Hello World!",
        "body": "..."
    }
}

Alternatively, if _source is not present, it will pop all metadata fields from the doc and use the rest as the document data:

{
    "_id": 42,
    "_routing": 5,
    "title": "Hello World!",
    "body": "..."
}

The bulk() api accepts index, create, delete, and update actions. Use the _op_type field to specify an action (_op_type defaults to index):

{
    '_op_type': 'delete',
    '_index': 'index-name',
    '_type': 'document',
    '_id': 42,
}
{
    '_op_type': 'update',
    '_index': 'index-name',
    '_type': 'document',
    '_id': 42,
    'doc': {'question': 'The life, universe and everything.'}
}

Example:¶

Lets say we have an iterable of data. Lets say a list of words called mywords and we want to index those words into individual documents where the structure of the document is like {"word": "<myword>"}.

def gendata():
    mywords = ['foo', 'bar', 'baz']
    for word in mywords:
        yield {
            "_index": "mywords",
            "word": word,
        }

bulk(es, gendata())

For a more complete and complex example please take a look at https://github.com/elastic/elasticsearch-py/blob/master/example/load.py#L76-L130

The parallel_bulk() api is a wrapper around the bulk() api to provide threading. parallel_bulk() returns a generator which must be consumed to produce results.

To see the results use:

for success, info in parallel_bulk(...):
if not success:
    print('A document failed:', info)

If you don’t care about the results, you can use deque from collections:

from collections import deque
deque(parallel_bulk(...), maxlen=0)

Note

When reading raw json strings from a file, you can also pass them in directly (without decoding to dicts first). In that case, however, you lose the ability to specify anything (index, type, even id) on a per-record basis, all documents will just be sent to elasticsearch to be indexed as-is.

elasticsearch.helpers.streaming_bulk(client, actions, chunk_size=500, max_chunk_bytes=104857600, raise_on_error=True, expand_action_callback=<function expand_action>, raise_on_exception=True, max_retries=0, initial_backoff=2, max_backoff=600, yield_ok=True, *args, **kwargs)¶

Streaming bulk consumes actions from the iterable passed in and yields results per action. For non-streaming usecases use bulk() which is a wrapper around streaming bulk that returns summary information about the bulk operation once the entire input is consumed and sent.

If you specify max_retries it will also retry any documents that were rejected with a 429 status code. To do this it will wait (by calling time.sleep which will block) for initial_backoff seconds and then, every subsequent rejection for the same chunk, for double the time every time up to max_backoff seconds.

Parameters:

client – instance of Elasticsearch to use
actions – iterable containing the actions to be executed
chunk_size – number of docs in one chunk sent to es (default: 500)
max_chunk_bytes – the maximum size of the request in bytes (default: 100MB)
raise_on_error – raise BulkIndexError containing errors (as .errors) from the execution of the last chunk when some occur. By default we raise.
raise_on_exception – if False then don’t propagate exceptions from call to bulk and just report the items that failed as failed.
expand_action_callback – callback executed on each action passed in, should return a tuple containing the action line and the data line (None if data line should be omitted).
max_retries – maximum number of times a document will be retried when 429 is received, set to 0 (default) for no retries on 429
initial_backoff – number of seconds we should wait before the first retry. Any subsequent retries will be powers of initial_backoff * 2**retry_number
max_backoff – maximum number of seconds a retry will wait
yield_ok – if set to False will skip successful documents in the output

elasticsearch.helpers.parallel_bulk(client, actions, thread_count=4, chunk_size=500, max_chunk_bytes=104857600, queue_size=4, expand_action_callback=<function expand_action>, *args, **kwargs)¶

Parallel version of the bulk helper run in multiple threads at once.

Parameters:

client – instance of Elasticsearch to use
actions – iterator containing the actions
thread_count – size of the threadpool to use for the bulk requests
chunk_size – number of docs in one chunk sent to es (default: 500)
max_chunk_bytes – the maximum size of the request in bytes (default: 100MB)
raise_on_error – raise BulkIndexError containing errors (as .errors) from the execution of the last chunk when some occur. By default we raise.
raise_on_exception – if False then don’t propagate exceptions from call to bulk and just report the items that failed as failed.
expand_action_callback – callback executed on each action passed in, should return a tuple containing the action line and the data line (None if data line should be omitted).
queue_size – size of the task queue between the main thread (producing chunks to send) and the processing threads.

elasticsearch.helpers.bulk(client, actions, stats_only=False, *args, **kwargs)¶

Helper for the bulk() api that provides a more human friendly interface - it consumes an iterator of actions and sends them to elasticsearch in chunks. It returns a tuple with summary information - number of successfully executed actions and either list of errors or number of errors if stats_only is set to True. Note that by default we raise a BulkIndexError when we encounter an error so options like stats_only only apply when raise_on_error is set to False.

When errors are being collected original document data is included in the error dictionary which can lead to an extra high memory usage. If you need to process a lot of data and want to ignore/collect errors please consider using the streaming_bulk() helper which will just return the errors and not store them in memory.

Parameters:	client – instance of `Elasticsearch` to use actions – iterator containing the actions stats_only – if True only report number of successful/failed operations instead of just number of successful and a list of error responses

Any additional keyword arguments will be passed to streaming_bulk() which is used to execute the operation, see streaming_bulk() for more accepted parameters.

Scan¶

elasticsearch.helpers.scan(client, query=None, scroll='5m', raise_on_error=True, preserve_order=False, size=1000, request_timeout=None, clear_scroll=True, scroll_kwargs=None, **kwargs)¶

Simple abstraction on top of the scroll() api - a simple iterator that yields all hits as returned by underlining scroll requests.

By default scan does not return results in any pre-determined order. To have a standard order in the returned documents (either by score or explicit sort definition) when scrolling, use preserve_order=True. This may be an expensive operation and will negate the performance benefits of using scan.

Parameters:

client – instance of Elasticsearch to use
query – body for the search() api
scroll – Specify how long a consistent view of the index should be maintained for scrolled search
raise_on_error – raises an exception (ScanError) if an error is encountered (some shards fail to execute). By default we raise.
preserve_order – don’t set the search_type to scan - this will cause the scroll to paginate with preserving the order. Note that this can be an extremely expensive operation and can easily lead to unpredictable results, use with caution.
size – size (per shard) of the batch send at each iteration.
request_timeout – explicit timeout for each call to scan
clear_scroll – explicitly calls delete on the scroll id via the clear scroll API at the end of the method on completion or error, defaults to true.
scroll_kwargs – additional kwargs to be passed to scroll()

Any additional keyword arguments will be passed to the initial search() call:

scan(es,
    query={"query": {"match": {"title": "python"}}},
    index="orders-*",
    doc_type="books"
)

Reindex¶

elasticsearch.helpers.reindex(client, source_index, target_index, query=None, target_client=None, chunk_size=500, scroll='5m', scan_kwargs={}, bulk_kwargs={})¶

Reindex all documents from one index that satisfy a given query to another, potentially (if target_client is specified) on a different cluster. If you don’t specify the query you will reindex all the documents.

Since 2.3 a reindex() api is available as part of elasticsearch itself. It is recommended to use the api instead of this helper wherever possible. The helper is here mostly for backwards compatibility and for situations where more flexibility is needed.

Note

This helper doesn’t transfer mappings, just the data.

Parameters:

client – instance of Elasticsearch to use (for read if target_client is specified as well)
source_index – index (or list of indices) to read documents from
target_index – name of the index in the target cluster to populate
query – body for the search() api
target_client – optional, is specified will be used for writing (thus enabling reindex between clusters)
chunk_size – number of docs in one chunk sent to es (default: 500)
scroll – Specify how long a consistent view of the index should be maintained for scrolled search
scan_kwargs – additional kwargs to be passed to scan()
bulk_kwargs – additional kwargs to be passed to bulk()

Added AddonClient class to allow for extending the client from outside

1.4.0 (2015-02-11)¶

Using insecure SSL configuration (verify_cert=False) raises a warning
reindex accepts a query parameter
enable reindex helper to accept any kwargs for underlying bulk and scan calls
when doing an initial sniff (via sniff_on_start) ignore special sniff timeout
option to treat TransportError as normal failure in bulk helpers
fixed an issue with sniffing when only a single host was passed in

1.3.0 (2014-12-31)¶

Timeout now doesn’t trigger a retry by default (can be overriden by setting retry_on_timeout=True)
Introduced new parameter retry_on_status (defaulting to (503, 504)) controls which http status code should lead to a retry.
Implemented url parsing according to RFC-1738
Added support for proper SSL certificate handling
Required parameters are now checked for non-empty values
ConnectionPool now checks if any connections were defined
DummyConnectionPool introduced when no load balancing is needed (only one connection defined)
Fixed a race condition in ConnectionPool

1.2.0 (2014-08-03)¶

Compatibility with newest (1.3) Elasticsearch APIs.
Filter out master-only nodes when sniffing
Improved docs and error messages

1.1.1 (2014-07-04)¶

Bugfix release fixing escaping issues with request_timeout.

1.1.0 (2014-07-02)¶

Compatibility with newest Elasticsearch APIs.
Test helpers - ElasticsearchTestCase and get_test_client for use in your tests
Python 3.2 compatibility
Use simplejson if installed instead of stdlib json library
Introducing a global request_timeout parameter for per-call timeout
Bug fixes

1.0.0 (2014-02-11)¶

Elasticsearch 1.0 compatibility. See 0.4.X releases (and 0.4 branch) for code compatible with 0.90 elasticsearch.
major breaking change - compatible with 1.0 elasticsearch releases only!
Add an option to change the timeout used for sniff requests (sniff_timeout).
empty responses from the server are now returned as empty strings instead of None
get_alias now has name as another optional parameter due to issue #4539 in es repo. Note that the order of params have changed so if you are not using keyword arguments this is a breaking change.

0.4.4 (2013-12-23)¶

helpers.bulk_index renamed to helpers.bulk (alias put in place for backwards compatibility, to be removed in future versions)
Added helpers.streaming_bulk to consume an iterator and yield results per operation
helpers.bulk and helpers.streaming_bulk are no longer limited to just index operations.
unicode body (for incices.analyze for example) is now handled correctly
changed perform_request on Connection classes to return headers as well. This is a backwards incompatible change for people who have developed their own connection class.
changed deserialization mechanics. Users who provided their own serializer that didn’t extend JSONSerializer need to specify a mimetype class attribute.
minor bug fixes

0.4.3 (2013-10-22)¶

Fixes to helpers.bulk_index, better error handling
More benevolent hosts argument parsing for Elasticsearch
requests no longer required (nor recommended) for install

0.4.2 (2013-10-08)¶

ignore param accepted by all APIs
Fixes to helpers.bulk_index

0.4.1 (2013-09-24)¶

Initial release.
