Compatibility

for Python V4.0.0 and later. Tablestore SDK for Python V4.x.x and Tablestore SDK for
Python V2.x.x are incompatible in the following respects:
- The package name is changed from ots2 to tablestore.
- The TableOptions parameter is added for the Client.create_table operation.
- The type of the primary_key parameter is changed from dict to list for the put_row, get_row, and update_row operations to ensure the sequence of primary keys.
- The type of the attribute_columns parameter is changed from dict to list for the put_row and update_row operations.
- The timestamp parameter is added to the attribute_columns parameter for the put_row and update_row operations.
- The max_version and time_range parameters are added for the get_row and get_range operations. You must specify at least one of max_version and time_range.
- The return_type parameter is added for the put_row, update_row, and delete_row operations. Only RT_PK is supported to return the primary key value of the current row.
- The return_row parameter is added for the put_row, update_row, and delete_row operations. If you set return_type to RT_PK in the request, the primary key value of the row is returned in return_row.
