Write multiple rows of data at the same time - Tablestore

Writes multiple rows of data at the same time. You can call this operation to insert, modify, or delete a row of data.

Request syntax

message BulkImportRequest {
    required string table_name = 1;
    repeated RowInBulkImportRequest rows = 2;
}

Parameter	Type	Required	Description
table_name	string	Yes	The name of the data table.
rows	repeated RowInBulkImportRequest	Yes	The row of data that you want to manage.

Response syntax

message BulkImportResponse {
    required string table_name = 1;
    repeated RowInBulkImportResponse rows = 2;
}

Parameter	Type	Required	Description
table_name	string	Yes	The name of the data table.
rows	repeated RowInBulkImportResponse	Yes	Indicates whether the write operation is successful, the error message, and the consumed capacity units (CUs). For more information, see Read and write throughput.

CU consumption

If the operation fails, no CUs are consumed.
If the request times out and the results are undefined, CUs may or may not be consumed.
If an internal error occurs and the HTTP status code 5xx is returned, the operation does not consume CUs. If other errors occur, one CU is consumed.
In other cases, RowInBulkImportRequest specifies the insert, update and delete operations, and the consumed CU is independently calculated based on the operation that is performed. The following content describes the calculation methods of CUs consumed by performing the insert, update, and delete operations on rows of data.
- When you insert a row of data, the number of consumed write CUs is rounded up from the value calculated based on the following formula: (Size of the data in all primary key columns of the row + Size of the data in the inserted attribute columns)/4 KB.
- When you update a row of data, the number of consumed write CUs is rounded up from the value calculated based on the following formula: (Size of the data in all primary key columns of the row + Size of the data in the updated attribute columns)/4 KB. If you want to delete an attribute column when you update a row of data, only the column name length is included in the data size of the attribute column.
- When you delete a row of data, the number of consumed write CUs is rounded up from the value calculated based on the following formula: Size of the data in all primary key columns of the row/4 KB.
