>
> The operations and queries involved with
> removeDuplicateCompletedTxnComponents are much costlier than the rest of the
> AcidHouseKeeper jobs. The default timer for
> metastore.acid.housekeeper.interval is 60s [0], which is much too frequent
> for removeDuplicateCompletedTxnComponents, but fine for the other operations.
> There is no way of lowering the internal for just
> removeDuplicateCompletedTxnComponents without impacting the other
> AcidHouseKeeper jobs, so I am requesting that it be split into its own
> process/timer
> [0]
