>
> Every local task store is backed up by a kafka changelog topic. Due to log
> compaction, delete tombstones of the changelog topic have a ttl of
> delete.retention.ms. Replaying the events from the changelog that has missing
> delete tombstones, would result in creation of an inconsistent local
> store(due to the missing of some delete events). This patch deletes the local
> stores in which difference between current time and last modified time of the
> offset file is greater than delete.retention.ms during the container startup.
