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.
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
.
It provides a more convenient and idiomatic way to write and manipulate
queries
_. It stays close to the Elasticsearch JSON DSL, mirroring its
terminology and structure 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.

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 <https://pypi.python.org/pypi/elasticsearch>
_::
pip install elasticsearch
Example use
Simple use-case::
>>> from datetime import datetime
>>> from elasticsearch1 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
