Request syntax

message DeleteTimeseriesMetaRequest {
  required string table_name = 1;

}

Parameter	Type	Required	Description
table_name	string	Yes	The name of the time series table.
timeseries_key	TimeseriesKey	Yes	The identifiers of the time series whose metadata you want to delete.
supported_table_version	int64	No	The model version number of the time series table supported by the Tablestore SDK. Valid values: 0: The model version number does not support time series tables that contain custom time series identifiers and data fields specified as the primary key columns. This is the default value. 1: The model version number supports time series tables that contain custom time series identifiers and data fields specified as the primary key columns. Note The schema specified by TimeseriesKey varies based on the model version number. If the model version number specified by the supported_table_version parameter is earlier than the model version number of the time series table on which you want to perform operations, an error occurs. If you want to develop your own Tablestore SDK, we recommend that you set this parameter to `1`.
