As stated if you compile it yourself once in a while you will always be fully updated instead of having to rely on the creator of the repack.
So, basically I suggest finding a guide on how to compile it yourself and then search for a database and a guide to connect it. A few databases I know of is whydb, rivaldb and ncdb. Should be links on the forum, I can't recall them directly but search for any of them and you should arrive at a helpful thread.
Hope I could help, good luck!
