-------------------------------
Summary: Replace c3p0 connection pool with HikariCP, upgrading
MySQL connector and Eclipselink
Key: RANGER-2895
URL: https://issues.apache.org/jira/browse/RANGER-2895
Project: Ranger
Issue Type: Improvement
Components: admin, Ranger
Reporter: RickyMa
We should replace c3p0 with
[HikariCP|[https://github.com/brettwooldridge/HikariCP]]. HikariCP is much
faster and less error prone. HikariCP is more popular with 13.2k+ stars on its
github. There were no more new commits since Nov 18, 2019 in
[c3p0|[https://github.com/swaldman/c3p0/commits/master]].
[MySQL connector|[https://github.com/mysql/mysql-connector-j]] and
[Eclipselink|[https://github.com/eclipse-ee4j/eclipselink]] should be upgraded
to the latest stable versions as well to include many essential bugfixes.
