> In 5-min snapshot processing of onAlertEvent method took ~94 seconds producing 46k commits and almost same amount of db requests (~equally split between alert_history and alert_definition tables)
> this can be related to large amount to alerts, but it should be addressed as we can have even more alerts on larger clusters, and it can be caused by a single thread only for all listeners, so there's possible bottleneck here.
