why if a request is timeout, the tcp connection will be closed

[Hongshun Wang]

Hi, devs,

I am curious about why if a request is timeout, the tcp connection will be
closed?[1] ?  When close a tcp connection, all the pending request will be
return    TimeoutException. Isn’t a waste?

I notice that connection.max.idle.ms[2] will close idle connections after
the number of milliseconds specified. Why we just return TimeoutException
for the target request, and not close the connection until
connection.max.idle.ms?

I do want to know the design idea. Much appreciate if anyone can answer me?


Best,
Hongshun
