In debug mode , execute SQL statement that was passed via environment .
To use this facility , you need to
1 . Add code DBUG_EXECUTE_MARIABACKUP_EVENT ( " my_event_name " , key ) ; ) ;
to the code . key is usually a table name
2 . Set environment variable my_event_name_ $ key SQL statement you want to execute
when event occurs , in DBUG_EXECUTE_IF from above .
In mtr , you can set environment via ' let ' statement ( do not use $ as the first char
for the variable )
3 . start mariabackup with - - dbug = + d , debug_mariabackup_events
