[jira] [Created] (HIVE-18840) CachedStore: Prioritize loading of recently accessed tables during prewarm

Vaibhav Gumashta created HIVE-18840:
---------------------------------------

             Summary: CachedStore: Prioritize loading of recently accessed tables during prewarm
                 Key: HIVE-18840
                 URL: https://issues.apache.org/jira/browse/HIVE-18840
             Project: Hive
          Issue Type: Bug
          Components: Metastore
    Affects Versions: 3.0.0
            Reporter: Vaibhav Gumashta


On clusters with large metadata, prewarming the cache can take several hours. Now that CachedStore does not block on prewarm anymore (after HIVE-18264), we should prioritize loading of recently accessed tables during prewarm.
