Spring Quartz Mysql Redis Poc

This poc is about getting some status from a cache, and a scheduler changes this cache based at some relational database.

Other point is that running more than one instance of the project only one instance should do the schedule job.

Usage

• docker-compose to start mysql and redis
• create tables (see database.sql)
• run application
• go to swagger-ui

Change schedule

Unfortunately the way to change cron is update at database 😞

UPDATE QRTZ_CRON_TRIGGERS
SET CRON_EXPRESSION = '0 0/5 * 1/1 * ? *'
WHERE TRIGGER_NAME = 'updateBankStatusCacheTrigger';

Created endpoint to do this. But quartz don't changes in real time 😞 . Only after the job is executed the new cron expression is used.
