-- Migration: Add index on locked_until for account lockout queries
|
|
-- Task: ST-4.1, GAP-009
|
|
-- Description: Creates a more optimized partial index for active account
|
|
-- lockouts, improving query performance on account unlock checks
|
|
-- ============================================================================
|
|
|
|
-- Drop the previous index if it exists (less specific)
|
|
DROP INDEX IF EXISTS auth.idx_users_locked CASCADE;
|
|
|
|
-- Create optimized partial index for active lockouts
|
|
CREATE INDEX idx_users_locked_until
|
|
ON auth.users(locked_until)
|
|
WHERE locked_until IS NOT NULL AND locked_until > NOW();
|
|
|
|
-- Add index comment
|
|
COMMENT ON INDEX auth.idx_users_locked_until IS 'Partial index for active account lockouts - optimized for unlock validation queries';
|

|
|
-- This index improves queries like:
|
|
-- SELECT id, email FROM auth.users WHERE locked_until > NOW();
|
|
--
|
|
-- Benefits:
|
|
-- 1. Smaller index size (only rows with active locks)
|
|
-- 2. Faster scans for checking unlocked accounts
|
|
-- 3. Automatic pruning as locks expire
