Fixed Bugs
-
PXC-749: Fixed memory leak when running
INSERT
on a table without primary key defined andwsrep_certify_nonPK
disabled (set to0
).NOTE: We recommend you define primary keys on all tables for correct write-set replication.
-
PXC-812: Fixed SST script to leave the DONOR keyring when JOINER clears the datadir.
-
PXC-813: Fixed SST script to use UTC time format.
-
PXC-816: Fixed hook for caching GTID events in asynchronous replication. For more information, see #1681831.
-
PXC-820: Enabled querying of
pxc_maint_mode
by another client during the transition period. -
PXC-823: Fixed SST flow to gracefully shut down JOINER node if SST fails because DONOR leaves the cluster due to network failure. This ensures that the DONOR is then able to recover to synced state when network connectivity is restored For more information, see #1684810.
-
PXC-824: Fixed graceful shutdown of Percona XtraDB Cluster node to wait until applier thread finishes.
Other Improvements
-
PXC-819: Added five new status variables to expose required values from
wsrep_ist_receive_status
andwsrep_flow_control_interval
as numbers, rather than strings that need to be parsed:wsrep_flow_control_interval_low
wsrep_flow_control_interval_high
wsrep_ist_receive_seqno_start
wsrep_ist_receive_seqno_current
wsrep_ist_receive_seqno_end
