      Description

      When handling an alarm snapshot (a copy of all the alarms from the database), the Drools engine will currently re-update all of the associated facts in working memory. For systems with a large number of alarms this can cause unnecessary overhead.

      We should only update alarms in when the alarms in the snapshot are different from the ones in memory.
