How would we go about doing that? Should we be the ones taking care of it?
I'm not sure that the DB credentials I currently have can delete content.
We can automate purging using the MariaDB using the Event Scheduler[1] if
you guys want a once-off-set-and-forget solution. Eg:
CREATE TABLE purge_schedule (
table_name varchar(100) NOT NULL,
days tinyint(3) unsigned NOT NULL
);
Then for each EL table you would do:
INSERT INTO purge_schedule VALUES ('MultimediaTiming_7193302', 30);
The rest would be left to me, or rather, to a couple of stored procedures
:-)
