Readme

Python Elasticsearch Async Client
=================================

This is an adapter for `elasticsearch-py`_ providing a transport layer based on
Python's `asyncio`_ module. All API calls now return a future wrapping the
response.

Sniffing (when requested) is also done via a scheduled coroutine.

Example for python 3.5+

.. code-block:: python

    import asyncio
    from elasticsearch_async import AsyncElasticsearch

    client = AsyncElasticsearch(hosts=['localhost', 'other-host'])

    async def print_info():
        info = await client.info()
        print(info)

    loop = asyncio.get_event_loop()
    loop.run_until_complete(print_info())
    loop.run_until_complete(client.transport.close())
    loop.close()

Example for python 3.4

.. code-block:: python

    import asyncio
    from elasticsearch_async import AsyncElasticsearch

    client = AsyncElasticsearch(hosts=['localhost', 'other-host'])

    @asyncio.coroutine
    def print_info():
        info = yield from client.info()
        print(info)

    loop = asyncio.get_event_loop()
    loop.run_until_complete(print_info())
    loop.run_until_complete(client.transport.close())
    loop.close()


Example with SSL Context

.. code-block:: python

    import asyncio
    from elasticsearch_async import AsyncElasticsearch
    from elasticsearch.connection.http_urllib3 import create_ssl_context

    context = create_ssl_context(cafile="/certs/ca/ca.crt")

    client = AsyncElasticsearch(
        hosts=['elasticsearch-xpack'],
        ssl_context=context,
        http_auth=('elastic', 'changeme')
    )

    @asyncio.coroutine
    def print_info():
        info = yield from client.info()
        print(info)

    loop = asyncio.get_event_loop()
    loop.run_until_complete(print_info())
    loop.run_until_complete(client.transport.close())
    loop.close()



``AsyncElasticsearch`` introduces one extra parameter ``loop`` which can be
used to pass in an event loop you wish the client to use. By default
``asyncio.get_event_loop()`` will be used.
