What difference between kyuubi.session.idle.timeout and kyuubi.session.engine.idle.timeout ?

[ethanzhou8109]

Is session.idle.timeout better to be longer than engine.idle.timeout ?

The session will be closed when not accessed for more than the kyuubi.session.idle.timeout and the engine will be closed when not accessed for more than the kyuubi.engine.idle.timeout.
So we only need to understand the relationship between session and engine, they are not one-to-one correspondence. For the session, we usually use it to close it after the use is complete, and the kyuubi.session.idle.timeout only handles some abnormal sessions. The CONNECTION level engine stops when the session is closed, and the shared engine will judge whether it needs to exit through kyuubi.engine.idle.timeout.
