Bugs Fixed

  • When replicating DML statements with IGNORE between clusters, the number of operations that failed due to nonexistent keys was expected to be no greater than the number of defined operations of any single type. Because the slave SQL thread defines operations of multiple types in batches together, code which relied on this assumption could cause mysqld to fail. (Bug #12859831)

  • When failure handling of an API node takes longer than 300 seconds, extra debug information is included in the resulting output. In cases where the API node's node ID was greater than 48, these extra debug messages could lead to a crash, and confuing output otherwise. This was due to an attempt to provide information specific to data nodes for API nodes as well. (Bug #62208)

  • In rare cases, a series of node restarts and crashes during restarts could lead to errors while reading the redo log. (Bug #62206)
