 As trino-lb cannot inspect the traffic in the subsequent calls, it would have no knowledge of the started and finished queries. However, an [HTTP event listener](https://trino.io/docs/current/admin/event-listeners-http.html) can be configured in Trino to inform trino-lb about all query starts and completions.
