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
