        # Create or update an alias.
        # Adds a data stream or index to an alias.
        #
        # @option arguments [String, Array] :index Comma-separated list of data streams or indices to add.
        #  Supports wildcards (`*`).
        #  Wildcard patterns that match both data streams and indices return an error. (*Required*)
        # @option arguments [String] :name Alias to update.
        #  If the alias doesn’t exist, the request creates it.
        #  Index alias names support date math. (*Required*)
        # @option arguments [Time] :master_timeout Period to wait for a connection to the master node.
        #  If no response is received before the timeout expires, the request fails and returns an error. Server default: 30s.
        # @option arguments [Time] :timeout Period to wait for a response.
        #  If no response is received before the timeout expires, the request fails and returns an error. Server default: 30s.
        # @option arguments [Boolean] :error_trace When set to `true` Elasticsearch will include the full stack trace of errors
        #  when they occur.
        # @option arguments [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
        #  `"eixsts_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
