Transport classes
=================

List of transport classes that can be used, simply import your choice and pass
it to the constructor of :class:`~elasticsearch.Elasticsearch` as
`connection_class`. Note that the
:class:`~elasticsearch.connection.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.
