Subject [jira] [Commented] (KAFKA-49) Add acknowledgement to the produce request.
Date Mon, 05 Mar 2012 22:43:57 GMT

Jun Rao commented on KAFKA-49:
------------------------------

Prashanth,

That's a good question. Initially, I was just thinking that for async producers, if we get
an error during send (after retries), we will just log the error without telling the client.
Currently, the event handler is not really extensible. I can image that we add some kind of
callback to return those errors. The question is what will the client do on those errors.
Will it resend? If so, we will need to pass the failed requests through callback too. I am
curious about how other messaging systems like activeMQ do in the async mode.

> Currently, the produce request doesn't get acknowledged. We need to have a broker send
a response to the producer and have the producer wait for the response before sending the
next request.
