-- Migration 11: Remove overly specific table indexes formerly used in sorting
|
|
-- When one or two indexed columns are used, sorting usually is fast
|
|
-- Reduces from ~78 indexes to 48 for better write performance,
|
|
-- reduced disk usage, and more reliable query planner decisions.
|
|
-- Requires ANALYZE to be run after migration (done automatically on startup).
|
|
|
|
-- ============================================================
|
|
-- Drop SELECTED existing job indexes (from migrations 08/09)
|
|
-- sqlite_autoindex_job_1 (UNIQUE constraint) is kept automatically
|
|
-- ============================================================
