Subject [jira] [Updated] (HIVE-13931) Add support for HikariCP connection pooling
Date Thu, 17 Nov 2016 18:28:58 GMT


Thejas M Nair updated HIVE-13931:
    Release Note: 
This change adds support for hikaricp as connection pooling library. It can be set via datanucleus.connectionPoolingType
in hive configuration.
The version of hikaricp being used requires java8 runtime or later and should be enabled only
when appropriate version of runtime is in use.

> 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.
