Central Db and run app next to each plex instance

Any chance of updating to use something like MariaDB and then instead of having one copy of the app you have one copy next to each plex instance so that it can read and write the DB without the restart or connection between the server? I would love to put this all in docker containers but my docker-compose files run as services that auto restart if any container stops so does not work with the current version that stops plex. Also i prefer a central data store because then other things could mark things as watched if it say monitoried netflix or emby or any other player or source out there.
