Compatibility

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

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

For Elasticsearch 1.0 and later, use the major version 1 (1.x.y) of the library.

For Elasticsearch 0.90.x, use a version from 0.4.x releases of the library.

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

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

# Elasticsearch 1.x
elasticsearch>=1.0.0,<2.0.0

# Elasticsearch 0.90.x
elasticsearch<1.0.0

The development is happening on master and 1.x branches, respectively.

Installation

Install the elasticsearch package with pip:

pip install elasticsearch

Example use

Simple use-case:

>>> from datetime import datetime
>>> from elasticsearch import Elasticsearch

# by default we connect to localhost:9200
>>> es = Elasticsearch()

# create an index in elasticsearch, ignore status code 400 (index already exists)
>>> es.indices.create(index='my-index', ignore=400)
{u'acknowledged': True}

# datetimes will be serialized
>>> es.index(index="my-index", doc_type="test-type", id=42, body={"any": "data", "timestamp": datetime.now()})
{u'_id': u'42', u'_index': u'my-index', u'_type': u'test-type', u'_version': 1, u'ok': True}

# but not deserialized
>>> es.get(index="my-index", doc_type="test-type", id=42)['_source']
{u'any': u'data', u'timestamp': u'2013-05-12T19:45:31.804229'}

Features

The client’s features include:

• translating basic Python data types to and from json (datetimes are not decoded for performance reasons)

• configurable automatic discovery of cluster nodes

• persistent connections

• load balancing (with pluggable selection strategy) across all available nodes

• failed connection penalization (time based - failed connections won’t be retried until a timeout is reached)

• support for ssl and http authentication

• thread safety

• pluggable architecture
