I know that people have asked why MPD doesn't use an SQL database in the past, and I know also that the reason has been performance.
I'm not disputing this, and I don't want to start any kind of flame war, but aside from performance the use of SQL does allow for more features (or for making such features much easier to implement): 1 - Smart / dynamic playlists via complex SQL queries 2 - Easy maintenance of the database by external utilities using standard SQL 3 - Housing database on different machine from MPD (likely to cause a performance hit, I know) 4 - MPD clustering (an unlikely use case for most of MPDs users, I admit) For me personally, the second option is actually a biggie - currently one cannot manage the MPD database at any kind of granular level. Asking mpd to do an 'update' on its music directory has never completed for me - on an NFS-mounted 100GB+ music library. When I add things to the database I add things by name (e.g. mpc update "Artist"), but if I move files around or want to remove music from MPD's library, there doesn't seem to be any command to do that. I can only do 'update' on parts of the library and hope that MPD picks up that files are deleted / changed. I notice that MPD will also only rescan files if their modification date has changed; there seems to be no way to force MPD to re-scan a file/directory regardless of its modification time (which is useful in some situations). If these commands/features were added, I'd probably have less of a need for SQL personally, although the first idea above would be nice. I should also emphasise that in my view this doesn't have to be an all-or-nothing decision. Why not use a database plugin, and default to the internal MPD database, but allow the option of using SQLite/MySQL/etc? Wouldn't this satisfy both those who don't care/need the performance and those who want the flexibility of SQL?
