     [ https://issues.apache.org/jira/browse/HIVE-26165?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Denys Kuzmenko updated HIVE-26165:
----------------------------------
    Description: Since operations that required an EXCLUSIVE lock were rewritten to READs non-blocking, we do not need READ locks anymore. That should improve ACID TXN concurrency.
