The official Python client for Elasticsearch.

Features

• Translating basic Python data types to and from JSON
• Configurable automatic discovery of cluster nodes
• Persistent connections
• Load balancing (with pluggable selection strategy) across available nodes
• Failed connection penalization (time based - failed connections won't be retried until a timeout is reached)
• Support for TLS and HTTP authentication
• Thread safety across requests
• Pluggable architecture
• Helper functions for idiomatically using APIs together

Installation

Install the elasticsearch package with pip <https://pypi.org/project/elasticsearch>_::

$ 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 <https://elasticsearch-py.readthedocs.io/en/master/async.html>_.

Compatibility

Language clients are forward compatible; meaning that clients support communicating with greater or equal minor versions of Elasticsearch. Elasticsearch language clients are only backwards compatible with default distributions and without guarantees made.

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

Documentation

Documentation for the client is available on elastic.co_ and Read the Docs_.

.. _available on elastic.co: https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/index.html .. _Read the Docs: https://elasticsearch-py.readthedocs.io

Quick Start

.. code-block:: python

# Import the client from the 'elasticsearch' module
>>> from elasticsearch import Elasticsearch

# Instantiate a client instance
>>> client = Elasticsearch("http://localhost:9200")

# Call an API, in this example `info()`
>>> resp = client.info()

# View the result
>>> resp
{
  "name" : "instance-name",
  "cluster_name" : "cluster-name",
  "cluster_uuid" : "cluster-uuid",
  "version" : {
    "number" : "7.14.0",
    ...
  },
  "tagline" : "You know, for Search"
}

You can read more about configuring the client_ in the documentation.
