I would love the option to store Emby's database in MySQL - I have a setup that serves around 30 people and I feel that there would be real performance gains by using a proper relational backend over SQLite (I'm presuming).
On top of this it would make life easier for me when reporting on watched status a cross users.
I have a question to all of you, who are interested in advances in this area.
In case that we would move into a direction like that, we surely wouldn't go just a half step. I mean that it should also be able to achieve true high availability. For high availability, you can't go with a single database server - you need a failover cluster setup, and that doesn't come for free - not even with MySQL (you' won't get far with 'community versions').
Such a setup would require at least $1000-
