Comment vider les logs dans la base de données ?

Si les tables des logs ca_change_log, ca_change_log_snapshots, ca_change_log_subjects sont trop remplies, il est possible de les vider : 

SET FOREIGN_KEY_CHECKS = 0;
SELECT @@FOREIGN_KEY_CHECKS;
DELETE FROM ca_change_log;
DELETE FROM ca_change_log_snapshots;
DELETE FROM ca_change_log_subjects;
SET FOREIGN_KEY_CHECKS = 1;
