             Summary: CachedStore: Store cached partitions within the table 
cache  
                 Key: HIVE-18264
                 URL: https://issues.apache.org/jira/browse/HIVE-18264
             Project: Hive
          Issue Type: Bug
            Reporter: Vaibhav Gumashta
            Assignee: Vaibhav Gumashta


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.
