Vaibhav Gumashta updated HIVE-18264:
------------------------------------
Description: Currently we have a separate cache for partitions and
partition col stats which results in some calls iterating through each of these
for retrieving/updating. We can get better performance by organizing
hierarchically. We should also make prewarm non-blocking (was: Currently we

> CachedStore: Store cached partitions/col stats within the table cache and
