Subject: Re: In Flight Requests
Hi David,
Each request sent to Kafka gets acknowledged. The protocol allows multiple
requests to be sent on a connection without waiting on a connection. The number
of requests
impact is the following: sending more than one request at a time is
good as you can have one request being sent while the previous one is being
processed. So allowing more than one in-flight request makes sense. However
allowing an unbounded number of in-flight requests is actually not a good
thing
I notice that there is parameter max.in.flight.requests.per.connection in the
ProducerConfig.java code that can be set. It is defaulted to 5.
This is not documented in the 0.8.2 documentation.

Is it something we should play with?
