Configuring Idle connection time CPP2 ThriftServer about fbthrift

[varunsharmagit]

We did verify closed connections by running netstat and finding the connections moving from ESTABLISHED to CLOSE_WAIT state.

server->setIdleTimeout(0)

^ this turns off the idle connection closing. At FB we do use smarter clients that automatically reconnect though, but we haven't open sourced that code.

HeaderClientChannel has a setCloseCallback() that you could use to implement that functionality, so you'd get an async notification that the server closed the client connection in the proxy

[varunsharmagit]

Thanks. Does the HeaderClientChannel's closeCallback get called when the backend server crashes/restarts - I believe that would also void the connection ?

[djwatson]

It fires on tcp close or tcp reset events, it doesn't do any active keepalive.
