Mirror Tables Created on Tables with NON-STANDARD partitions will miss data #63

Closed dstreev closed 1 year ago

dstreev commented 1 year ago

The SQL strategy build a MIRROR table on the RIGHT cluster that points to the LEFT storage. Only the table definition is used to create the table. If the table has partitions, the MSCK REPAIR issued to discover them before the transfer, won't link the data.

Hence the transfer will NOT be complete.
