MyRocks and START TRANSACTION WITH CONSISTENT SNAPSHOT
FB/MySQL has added new syntax:
START TRANSACTION WITH CONSISTENT ROCKSDB|INNODB SNAPSHOT;
The statement returns the binlog coordinates pointing at the snapshot.
MariaDB (and Percona Server) support extension to the regular
START TRANSACTION WITH CONSISTENT SNAPSHOT;
syntax as documented in Enhancements for START TRANSACTION WITH CONSISTENT SNAPSHOT.
After issuing the statement, one can examine the binlog_snapshot_file and binlog_snapshot_position status variables to see the binlog position that corresponds to the snapshot.
