Jun Rao commented on KAFKA-1282:
--------------------------------

Nicu,

Similar to producers, consumers just issue fetch requests. The SocketServer 
first reads the fetch request from the network and then writes the fetch 
response to the network once the fetch request is served by the broker. So, 
there is a 1-to-1 mapping btw reads and writes and writes typically happen 
within a second after the reads.

> To reduce # socket connections, it would be useful for the new producer to 
> close socket connections that are idle. We can introduce a new producer 
> config for the idle time.
