Add functionality to Percona Server and XtraBackup to support lightweight locks
Registered by
Vadim Tkachenko
This is to implement support for backup locks in Percona XtraBackup. For the server-side part see https:/
When backup locks are supported by the server, use the following procedure instead of FLUSH TABLES WITH READ LOCK.
# copy InnoDB data
LOCK TABLES FOR BACKUP;
# copy .frm, MyISAM, etc
LOCK BINLOG FOR BACKUP;
# finalize the background copy of REDO log
# get the binary log coordinates
UNLOCK BINLOG;
UNLOCK TABLES;
