MariaDB quietly releases mariadb/mysql driver-level connection pool
Documentation: https://mariadb.com/kb/en/library/pool-datasource-implementation/
There is a (non-existant) discussion about the feature on JIRA: https://jira.mariadb.org/browse/CONJ-522 . It is to me unclear how this compares to HikariCP etc as I can´t find any benchmarks yet.
