> 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]] should be
> upgraded to the latest stable versions as well to include many essential
> bugfixes.
