Anishek Agarwal commented on HIVE-24070:
----------------------------------------
can you give some more details on this please, i thought the config introduced
as part of HIVE-19430 allows us to control how many events we want to delete.
however looks like there should be an inner loop since if the number of events
generated in sleepTime are more than deleted due to EVENT_CLEAN_MAX_EVENTS then
the db will never get cleaned.
