-- Convert all tailnet coordination tables to UNLOGGED for improved write performance.
|
|
-- These tables contain ephemeral coordination data that can be safely reconstructed
|
|
-- after a crash. UNLOGGED tables skip WAL writes, significantly improving performance
|
|
-- for high-frequency updates like coordinator heartbeats and peer state changes.
|
|
--
|
|
-- IMPORTANT: UNLOGGED tables are truncated on crash recovery and are not replicated
|
|
-- to standby servers. This is acceptable because:
|
|
-- 1. Coordinators re-register on startup
|
|
-- 2. Peers re-establish connections on reconnect
|
|
-- 3. Tunnels are re-created based on current peer state
|
|
|
|
-- Convert child tables first (they have FK references to tailnet_coordinators).
|
|
-- UNLOGGED child tables can reference LOGGED parent tables, but LOGGED child
|
|
-- tables cannot reference UNLOGGED parent tables. So we must convert children
|
|
-- before converting the parent.
|
|
ALTER TABLE tailnet_tunnels SET UNLOGGED;

ALTER TABLE tailnet_peers SET UNLOGGED;

|

-- Convert parent table last (after all children are unlogged).
