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 that fk-reference-table is open before marking it open.
