Review comment:
Are you cleaning the whole cache when tez task doesn't have any deltas
to report? What about data from other tasks that touched diff
tables/partitions.

Review comment:
Would it work as topN cache? It's gonna evict entry when the limit is
exceeded, even if that entry has a higher value than inserted
(least-recently-used eviction)

Why do you need a blocking queue here? Would it be accessed by multiple

Review comment:
This is supposed to be a global cache. I am not sure I understand it
right. But looks like if some part is not present in tez counters it would be
removed from global cache.
