Subject [jira] [Commented] (HIVE-13931) Add support for HikariCP connection pooling
Date Wed, 23 Nov 2016 00:53:58 GMT


Lefty Leverenz commented on HIVE-13931:

Doc note:  This adds a new value for *datanucleus.connectionPoolingType* in,
so the wiki description needs to be updated for release 2.2.0.  The parameter could also be
documented in the Metastore Administration doc (although it would go in a table that omits
most of the datanucleus parameters and has a disclaimer about being obsolete).

* [Configuration Properties -- datanucleus.connectionPoolingType |]
* [Metastore Administration -- Additional Configuration Parameters |]

Added a TODOC2.2 label.

> Currently, we use BoneCP as our primary connection pooling mechanism (overridable by
users). However, BoneCP is no longer being actively developed, and is considered deprecated,
replaced by HikariCP.
> Thus, we should add support for HikariCP, and try to replace our primary usage of BoneCP
with it.
> Note : bonecp is still the default for now, the version of hikaricp being used requires
java 8 runtime.
