--lock-ddl-per-table

This is a command-line option for the mariadb-backup & mariabackup commands.

This option tells MariaDB Backup to obtain a read metadata lock for each table, which can prevent concurrent DDL from occurring during the backup. Before the backup starts, MariaDB Backup acquires a metadata lock for each individual table on the system. The metadata locks are released when the backup completes.
