+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
