Python Elasticsearch Client

Official low-level client for Elasticsearch. It's 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:

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()

# 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'}

Full documentation.

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 availible nodes
• failed connection penalization (time based - failed connections won't be retried until a timeout is reached)
• thread safety
• pluggable architecture

Versioning

There are two branches for development - master and 0.4. Master branch is used to track all the changes for Elasticsearch 1.0 and beyond whereas 0.4 tracks Elasticsearch 0.90.

Releases with major version 1 (1.X.Y) are to be used with Elasticsearch 1.0 and later, 0.4 releases are meant to work with Elasticsearch 0.90.X.
