95b8d9dd04Filtering by genre scanned every media_file/album row and JSON-parsed its `tags` column (a per-row json_tree(tags) EXISTS) with no usable index, so Finamp's genre screen took 1.9-6.5s per tap against a ~97k-track library. Album and album-artist genre queries had the same unindexed shape. Add normalized media_file_tags and album_tags join tables (genre only for now, via an indexedTagNames allowlist), populated by a new updateTags in Put (mirroring updateParticipants) and backfilled in the migration. Genre filtering across the Jellyfin, Subsonic and native APIs now runs as an index-backed semi-join through shared TagIDSemiJoin/TagNameSemiJoin helpers instead of a full scan. On a copy of the production DB the per-request cost for a typical genre drops from ~330ms to sub-millisecond, adding ~10MB. |
