Deluan Quintão dbd26ba2e7 perf(scanner): improve playlist importing on large libraries (#6055) ... * perf(persistence): avoid a full media_file scan when resolving playlist paths FindByPaths built one OR-ed equality term per path. On the real media_file schema SQLite abandons the path index at just two OR-ed terms and falls back to SCAN media_file, re-testing every term against every row, so the cost grows with (rows x terms). Group the candidates by library and emit one IN list per library instead, which plans as SEARCH media_file USING INDEX media_file_path_nocase. The NOCASE collation is kept so ASCII case-insensitive matching still works. This is the dominant cost of M3U playlist import, which resolves every track on every scan. Measured with a 1000-track playlist against a migrated DB: 100k media_file rows: 397 -> 51,414 tracks/sec 500k media_file rows: 78.5 -> 47,174 tracks/sec The rate no longer degrades as the table grows, which is the expected shape for an index lookup. Reported in #6043, where an 8 hour scan of a 2M-song library spent 7h52m in the playlist phase. * docs(playlists): correct the stale reason for the M3U lookup chunk size The expression-tree depth ceiling applied to the old OR-per-path query, which capped a batch at roughly 500 terms. The IN form is bound by SQLite's 32766 variable limit instead, which the 400 candidates per chunk sit far below.		2026-08-30 22:17:25 -04:00
