MariaDB 10.X docker image with ROCKSDB engine
Based on official mariadb image (https://github.com/MariaDB/mariadb-docker), with all the options supported, see this page for the manual: https://hub.docker.com/_/mariadb/.
The default rocksdb.cnf from the debian package mariadb-plugin-rocksdb is saved as /etc/mysql/mariadb.conf.d/rocksdb.cnf but files from that folder are not included in the configuration. In order to have the plugin running, run container with -v /path/to/conf.d:/etc/mysql/conf.d (see conf.d/rocksdb.cnf).
