MySQL Events Summary

Events Summary

MySQL Events are database-native scheduled tasks. Use them for data archiving, session cleanup, statistics, leaderboard resets, and pre-computed reports. Enable the event scheduler, add error handling, and log executions to an audit table.

Example

-- Events checklist:
-- [x] event_scheduler = ON (my.cnf)
-- [x] DELIMITER change for multi-statement events
-- [x] DECLARE EXIT HANDLER for error logging
-- [x] INSERT INTO event_audit after each run
-- [x] Disable on replicas to avoid duplication
-- [x] Schedule heavy work during off-peak hours
-- [x] Batch deletes with LIMIT to avoid lock spikes

Pro Tip

Events complement application schedulers (cron, Celery, Laravel) — use each where it fits best.
