Subject [jira] [Commented] (HIVE-12441) Driver.acquireLocksAndOpenTxn() should only call recordValidTxns() when needed
Date Tue, 09 Feb 2016 21:55:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15139854#comment-15139854

Wei Zheng commented on HIVE-12441:
----------------------------------

This essentially will avoid having too much unnecessary logging for non-ACID table, especially
in extreme cases where there are hundreds of thousands of transactions

> recordValidTxns() is only needed if ACID tables are part of the query.  Otherwise it's
just overhead.
