После https://calcite.apache.org/docs/tutorial.html, Я запустил Apache Calcite с помощью SqlLine.Я попытался активировать трассировку, как указано в https://calcite.apache.org/docs/howto.html#tracing. Однако я не получаю никаких записей.Вот содержание моего сеанса (надеюсь, содержащего всю необходимую информацию):

Итак, теперь вопрос: как мне заставить SqlLine / Calcite регистрировать что-либо (в частности, меня интересует запросжурнал оптимизации).
