Summary: Use ConcurrentHashMap for CachedStore Key: HIVE-18039 URL: https://issues.apache.org/jira/browse/HIVE-18039 Project: Hive Issue Type: Improvement Components: Hive Affects Versions: 3.0.0 Reporter: Alexander Kolbasov SharedCache used by CachedStore uses single big lock to synchronize all access. This looks like an overkill - looks like it is possible to use ConcurrentHashMap instead. Also it makes sense to move deepCopy() operations outside the lock to reduce lock hold times. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
