-- Narrow ORDER BY for node access logs to match common filter patterns.
-- Requires ClickHouse 24.10+ (MODIFY ORDER BY). On older versions this statement
-- may fail and require manual table recreation; TTL changes above are still safe.
ALTER TABLE of_node_access_logs MODIFY ORDER BY (node_id, logged_at, status_code);
-- +goose Down
-- TTL and ORDER BY changes cannot be safely reversed without recreating tables.
