Percona has removed an Oracle patch for
mysqldump that performed, at the beginning of the dump, a
FLUSH_TABLES_WITH_READ_LOCK to get consistent
GTID_EXECUTED because the patch required additional user privileges, even when the user does not use GTID-based replication. The following bugs based on this patch were submitted to Oracle:
The Percona solution uses
START TRANSACTION WITH CONSISTENT SNAPSHOT.
Improvements and bug fixes provided by Oracle for MySQL 5.7.41 and included in Percona Server for MySQL are the following:
Updated the linked OpenSSL library for MySQL Server to 1.1.s
Updated the bundled zlib library to zlib 1.2.13. This zlib library version is the minimum supported.
While the SQL thread handled a transaction, issuing
STOP SLAVE_SQL_THREADcaused replication to stop immediately instead of waiting for the event group to complete before the shutdown.
