-- IM Kafka foundation tables for tenant databases.
|
|
-- Date: 2026-08-26
|
|
-- Scope: run once in every tenant business database, such as tinode.
|
|
-- Notes:
|
|
-- * Do not run in hotgo. Admin/HotGo side needs its own admin_command tables.
|
|
-- * Kafka consume idempotency/retry state is Redis-backed; MySQL only keeps manual dead letters.
