---------------------------------------
Summary: CachedStore: Use metastore notification log events to
update cache
Key: HIVE-18661
URL: https://issues.apache.org/jira/browse/HIVE-18661
Project: Hive
Issue Type: Bug
Components: Metastore
Reporter: Vaibhav Gumashta
Currently, a background thread updates the entire cache which is pretty
inefficient. We capture the updates to metadata in NOTIFICATION_LOG table which
is getting used in the Replication work. We should have the background thread
apply these notifications to incrementally update the cache.
