tdsql > SELECT * FROM information_schema.LOGSERVICE_MYSQL_UNSUPPORTED_TABLE\\G*************************** 1. row ***************************table_type: hidden_pk_tabletable_name: test.log_events1 row in set (0.02 sec)
test.log_events is not supported by the disaster recovery feature because it is a hidden primary key table (hidden_pk_table). It is recommended to add explicit primary keys to such tables to ensure they can be synchronized normally. If the query returns no results, it indicates that all current tables are compatible with the disaster recovery feature.Was this page helpful?
