-- Gameserver Database Optimization Migration
-- =============================================================================
-- This migration optimizes the gameserver tables (not website_* tables).
--
-- IMPORTANT: This script is designed to run on a POPULATED database safely.
-- It uses IF NOT EXISTS / IF EXISTS where possible.
--
-- What it does:
--   1. Converts Aria/MyISAM tables to InnoDB (required for foreign keys)
--   2. Fixes data type mismatches (unsigned/signed) so FKs can be created
--   3. Adds missing primary keys and indexes
--   4. Adds foreign key constraints for referential integrity
--
-- BEFORE RUNNING:
--   - Back up your database!
--   - Run on a test environment first
--   - The script disables FK checks during migration to avoid ordering issues

-- =============================================================================
-- Foreign keys require InnoDB. Converting Aria and MyISAM tables.
-- InnoDB does not support ROW_FORMAT=FIXED, so all tables get ROW_FORMAT=DYNAMIC.
-- Note: Aria tables lose PAGE_CHECKSUM (InnoDB has its own checksumming).

--   RESTRICT = prevent parent deletion if children exist (default)
--
-- NOTE: Log/archive tables (chatlogs, commandlogs, room_enter_log, etc.)
-- intentionally do NOT get FKs to avoid cascade-deleting historical data
-- and to keep high-volume inserts fast.
