> If for some reason housekeeper service wasn't running, when activated it could cause OOM. showCompactions & purgeCompactionHistory loads the complete history of events into the heap that should be reviewed.
> purgeCompactionHistory might be refactored with batching or replaced with a complex delete query instead of `select` first and then `delete`.
