Subject [jira] [Commented] (HIVE-16383) Switch to HikariCP as default connection pooling
Date Mon, 24 Apr 2017 08:04:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16383?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15980828#comment-15980828

Lefty Leverenz commented on HIVE-16383:
---------------------------------------

Thanks for the fix, Prasanth.

Doc note addendum:  HIVE-16321 adds *datanucleus.connectionPool.maxPoolSize* to branch-2.3
and branch-2 for releases 2.3.0 and 2.4.0, so it should be documented for 2.3.0 instead of
3.0.0.

> Since 3.0 is planned to move to JDK8, we can now switch to HikariCP as default connection
pooling for DN because of its improved performance over others.
