Percona XtraDB Cluster 5.6.30-25.16¶
Percona is glad to announce the release of Percona XtraDB Cluster 5.6.30-25.16 on June 10, 2016. Binaries are available from the downloads section or from our software repositories.
Percona XtraDB Cluster 5.6.30-25.16 is now the current release, based on the following:
- Percona Server 5.6.30-76.3
- Galera Replication library 3.16
- wsrep API version 25
All Percona software is open-source and free. Details of this release can be found in the 5.6.30-25.16 milestone on Launchpad.
For more information about relevant Codership releases, see this announcement.
New Features¶
- PXC now uses
wsrep_desync_count
introduced in Galera 3.16 by Codership, instead of the concept that was previously implemented by Percona. The following logic applies:- If a node is explicitly desynced, then implicitly desyncing a node using RSU/FTWRL is allowed.
- If a node is implicitly desynced using RSU/FTWRL, then explicitly desyncing a node is blocked until implicit desync is complete.
- If a node is explicitly desynced and then implicitly desycned using RSU/FTWRL, then any request for another implicit desync is blocked until the former implicit desync is complete.
Fixed Bugs¶
- Changing
wsrep_provider
while node is paused or desynced is not allowed. - TOI now checks that a node is ready to process DDL and DML before starting execution, to prevent node from crashing if it becomes non-primary.
- The
wsrep_row_upd_check_foreign_constraints
function now checks thatfk-reference-table
is open before marking it open.
