        # Update a datafeed.
        # You must stop and start the datafeed for the changes to be applied.
        # When Elasticsearch security features are enabled, your datafeed remembers which roles the user who updated it had at
        # the time of the update and runs the query using those same roles. If you provide secondary authorization headers,
        # those credentials are used instead.
        #
        # @option arguments [String] :datafeed_id A numerical character string that uniquely identifies the datafeed.
        #  This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores.
        #  It must start and end with alphanumeric characters. (*Required*)
        # @option arguments [Boolean] :allow_no_indices A setting that does two separate checks on the index expression.
        #  If `false`, the request returns an error (1) if any wildcard expression
        #  (including `_all` and `*`) resolves to zero matching indices or (2) if the
        #  complete set of resolved indices, aliases or data streams is empty after all
        #  expressions are evaluated. If `true`, index expressions that resolve to no
        #  indices are allowed and the request returns an empty result. Server default: true.
        # @option arguments [String, Array<String>] :expand_wildcards Type of index that wildcard patterns can match. If the request can target data streams, this argument determines
        #  whether wildcard expressions match hidden data streams. Supports comma-separated values. Server default: open.
        # @option arguments [Boolean] :ignore_throttled If `true`, concrete, expanded or aliased indices are ignored when frozen. Server default: true.
        # @option arguments [Boolean] :ignore_unavailable If `false`, the request returns an error if it targets a concrete (non-wildcarded)
        #  index, alias, or data stream that is missing, closed, or otherwise unavailable.
        #  If `true`, unavailable concrete targets are silently ignored.
        # @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
        # @option arguments [Hash] :body request body
        #
