HI Hasitha, The time interval it takes to catch the expired messages and time interval to delete the expired messages cant be different. Most probable latter time interval can be longer than the first one. WDYT?
There is no harm doing a performance test and decide. But I think since this is used for internal work and this value will be very rarely changed from environment to environment, we don't need to make this configurable.
