Alerts flush: Optimization of the flush mechanism (batch and limit to one job) + add cscli alerts flush
command (#1024)
- Don't allow running more than one alert flush job at a time to prevent runaway CPU usage in some case. (fix High CPU after Upgrade to 1.2.0 #1022) - Add a cscli alerts flush command to manually flush the alerts in the database (fixes Improvement/Manual flush mechanism #1023 ). - Enable cascading deletion on alerts as we upgraded ent: Deleting an alert in the database will automatically delete all related decisions, events and meta - Add an index on alerts.id to try to improve flush performance with very big sqlite database. - Flush alert now operates in batch
