        # Update field mappings.
        # Add new fields to an existing data stream or index.
        # You can also use this API to change the search settings of existing fields and add new properties to existing object fields.
        # For data streams, these changes are applied to all backing indices by default.
        # **Add multi-fields to an existing field**
        # Multi-fields let you index the same field in different ways.
        # You can use this API to update the fields mapping parameter and enable multi-fields for an existing field.
        # WARNING: If an index (or data stream) contains documents when you add a multi-field, those documents will not have values for the new multi-field.
        # You can populate the new multi-field with the update by query API.
        # **Change supported mapping parameters for an existing field**
        # The documentation for each mapping parameter indicates whether you can update it for an existing field using this API.
        # For example, you can use the update mapping API to update the +ignore_above+ parameter.
        # **Change the mapping of an existing field**
        # Except for supported mapping parameters, you can't change the mapping or field type of an existing field.
        # Changing an existing field could invalidate data that's already indexed.
        # If you need to change the mapping of a field in a data stream's backing indices, refer to documentation about modifying data streams.
        # If you need to change the mapping of a field in other indices, create a new index with the correct mapping and reindex your data into that index.
        # **Rename a field**
        # Renaming a field would invalidate data already indexed under the old field name.
        # Instead, add an alias field to create an alternate field name.
        #
        # @option arguments [String, Array] :index A comma-separated list of index names the mapping should be added to (supports wildcards); use +_all+ or omit to add the mapping on all indices. (*Required*)
        # @option arguments [Boolean] :allow_no_indices If +false+, the request returns an error if any wildcard expression, index alias, or +_all+ value targets only missing or closed indices.
        #  This behavior applies even if the request targets other open indices. 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, such as +open,hidden+.
        #  Valid values are: +all+, +open+, +closed+, +hidden+, +none+. Server default: open.
        # @option arguments [Boolean] :ignore_unavailable If +false+, the request returns an error if it targets a missing or closed index.
        # @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] :write_index_only If +true+, the mappings are applied only to the current write index for the target.
        # @option arguments [Hash] :headers Custom HTTP headers
        # @option arguments [Hash] :body request body
