Default time `start()` waits for the change-notify triggers and the channel subscriptions to be confirmed, in milliseconds.

**Signature:**

```typescript
DEFAULT_INVALIDATION_TIMEOUT = 30000
```

## Remarks

Reaching it means the database accepted a connection but the invalidation setup never finished, which is a broken deployment rather than a slow one: long enough not to trip on a loaded database, short enough that a service cannot sit in `start()` indefinitely.
