Compatibility
Table Store is compatible with Python SDK v4.x.x.
Table Store is incompatible with Python SDK v2.x.x, because Python SDK v2.x.x supports out-of-order primary keys. Detailed incompatibilities include:
- The name of the SDK is changed from ots2 to tablestore.
- The Client.create_table operation is added with the TableOptions parameter.
- The primary_key parameter for the put_row, get_row, and update_row operations is changed from the dict type to the list type to guarantee sequence.
- The attribute_columns parameter for the put_row and update_row operations is changed from the dict type to the list type.
- The attribute_columns parameter for the put_row and update_row operations is added with timestamp.
- The get_row and get_range operations are added with the max_version and time_range parameters. At lease one parameter must exist.
- The put_row, update_row, and delete_row operations are added with the return_type parameter. Currently, only RT_PK is supported, indicating that the returned value contains the PK value of the current row.
- The values returned by the put_row, update_row, and delete_row operations are added with return_row. If return_type is specified as RT_PK in a request, return_row contains the PK value of the current row.
