        # Get datafeeds configuration info.
        # You can get information for multiple datafeeds in a single API request by
        # using a comma-separated list of datafeeds or a wildcard expression. You can
        # get information for all datafeeds by using `_all`, by specifying `*` as the
        # `<feed_id>`, or by omitting the `<feed_id>`.
        # This API returns a maximum of 10,000 datafeeds.
        #
        # @option arguments [String, Array] :datafeed_id Identifier for the datafeed. It can be a datafeed identifier or a
        #  wildcard expression. If you do not specify one of these options, the API
        #  returns information about all datafeeds.
        # @option arguments [Boolean] :allow_no_match Specifies what to do when the request:
        #  - Contains wildcard expressions and there are no datafeeds that match.
        #  - Contains the `_all` string or no identifiers and there are no matches.
        #  - Contains wildcard expressions and there are only partial matches.
        #  The default value is `true`, which returns an empty `datafeeds` array
        #  when there are no matches and the subset of results when there are
        #  partial matches. If this parameter is `false`, the request returns a
        #  `404` status code when there are no matches or only partial matches.
        # @option arguments [Boolean] :exclude_generated Indicates if certain fields should be removed from the configuration on
        #  retrieval. This allows the configuration to be in an acceptable format to
        #  be retrieved and then added to another cluster.
        # @option arguments [Boolean] :error_trace When set to `true` Elasticsearch will include the full stack trace of errors
        #  when they occur.
        # @option arguments [String, Array<String>] :filter_path Comma-separated list of filters in dot notation which reduce the response
        #  returned by Elasticsearch.
        # @option arguments [Boolean] :human When set to `true` will return statistics in a format suitable for humans.
        #  For example `"exists_time": "1h"` for humans and
        #  `"exists_time_in_millis": 3600000` for computers. When disabled the human
        #  readable values will be omitted. This makes sense for responses being consumed
        #  only by machines.
        # @option arguments [Boolean] :pretty If set to `true` the returned JSON will be "pretty-formatted". Only use
        #  this option for debugging only.
        # @option arguments [Hash] :headers Custom HTTP headers
        #
