class Elasticsearch(object):
    """
    Elasticsearch low-level client. Provides a straightforward mapping from
    Python to ES REST endpoints.

    The instance has attributes ``cat``, ``cluster``, ``indices``, ``ingest``,
    ``nodes``, ``snapshot`` and ``tasks`` that provide access to instances of
    :class:`~elasticsearch.client.CatClient`,
    :class:`~elasticsearch.client.ClusterClient`,
    :class:`~elasticsearch.client.IndicesClient`,
    :class:`~elasticsearch.client.IngestClient`,
    :class:`~elasticsearch.client.NodesClient`,
    :class:`~elasticsearch.client.SnapshotClient` and
    :class:`~elasticsearch.client.TasksClient` respectively. This is the
    preferred (and only supported) way to get access to those classes and their
    methods.

    You can specify your own connection class which should be used by providing
    the ``connection_class`` parameter::

        # create connection to localhost using the ThriftConnection
        es = Elasticsearch(connection_class=ThriftConnection)

    If you want to turn on :ref:`sniffing` you have several options (described
    in :class:`~elasticsearch.Transport`)::

        # create connection that will automatically inspect the cluster to get
        # the list of active nodes. Start with nodes running on 'esnode1' and
        # 'esnode2'
        es = Elasticsearch(
            ['esnode1', 'esnode2'],
            # sniff before doing anything
            sniff_on_start=True,
            # refresh nodes after a node fails to respond
            sniff_on_connection_fail=True,
            # and also every 60 seconds
            sniffer_timeout=60
        )

    Different hosts can have different parameters, use a dictionary per node to
    specify those::

        # connect to localhost directly and another node using SSL on port 443
        # and an url_prefix. Note that ``port`` needs to be an int.
        es = Elasticsearch([
            {'host': 'localhost'},
            {'host': 'othernode', 'port': 443, 'url_prefix': 'es', 'use_ssl': True},
        ])

    If using SSL, there are several parameters that control how we deal with
    certificates (see :class:`~elasticsearch.Urllib3HttpConnection` for
    detailed description of the options)::

        es = Elasticsearch(
            ['localhost:443', 'other_host:443'],
            # turn on SSL
            use_ssl=True,
            # make sure we verify SSL certificates
            verify_certs=True,
            # provide a path to CA certs on disk
            ca_certs='/path/to/CA_certs'
        )

    If using SSL, but don't verify the certs, a warning message is showed
    optionally (see :class:`~elasticsearch.Urllib3HttpConnection` for
    detailed description of the options)::

        es = Elasticsearch(
            ['localhost:443', 'other_host:443'],
            # turn on SSL
            use_ssl=True,
            # no verify SSL certificates
            verify_certs=False,
            # don't show warnings about ssl certs verification
            ssl_show_warn=False
        )

    SSL client authentication is supported
    (see :class:`~elasticsearch.Urllib3HttpConnection` for
    detailed description of the options)::

        es = Elasticsearch(
            ['localhost:443', 'other_host:443'],
            # turn on SSL
            use_ssl=True,
            # make sure we verify SSL certificates
            verify_certs=True,
            # provide a path to CA certs on disk
            ca_certs='/path/to/CA_certs',
            # PEM formatted SSL client certificate
            client_cert='/path/to/clientcert.pem',
            # PEM formatted SSL client key
            client_key='/path/to/clientkey.pem'
        )

    Alternatively you can use RFC-1738 formatted URLs, as long as they are not
    in conflict with other options::

        es = Elasticsearch(
            [
                'http://user:secret@localhost:9200/',
                'https://user:secret@other_host:443/production'
            ],
            verify_certs=True
        )

    By default, `JSONSerializer
    <https://github.com/elastic/elasticsearch-py/blob/master/elasticsearch/serializer.py#L24>`_
    is used to encode all outgoing requests.
    However, you can implement your own custom serializer::

        from elasticsearch.serializer import JSONSerializer

        class SetEncoder(JSONSerializer):
            def default(self, obj):
                if isinstance(obj, set):
                    return list(obj)
                if isinstance(obj, Something):
                    return 'CustomSomethingRepresentation'
                return JSONSerializer.default(self, obj)

        es = Elasticsearch(serializer=SetEncoder())
