During backup, loading data from one SQL node followed by repeated
DELETEstatements on the tables just loaded from a different SQL node could lead to data node failures. (Bug #18949230)
When an instance of
NdbEventBufferwas destroyed, any references to GCI operations that remained in the event buffer data list were not freed. Now these are freed, and items from the event bufer data list are returned to the free list when purging GCI containers. (Bug #76165, Bug #20651661)
When a bulk delete operation was committed early to avoid an additional round trip, while also returning the number of affected rows, but failed with a timeout error, an SQL node performed no verification that the transaction was in the Committed state. (Bug #74494, Bug #20092754)
