Subject [jira] [Commented] (KAFKA-683) Fix correlation ids in all requests sent to kafka
Date Thu, 10 Jan 2013 19:18:13 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-683?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13549953#comment-13549953

Jun Rao commented on KAFKA-683:
-------------------------------

I agree that seeing the whole request is not useful, especially Message, since it's binary.
Maybe what we should do is to fix the toString() method in each request so that it only prints
out meaningful info. This can be fixed in a separate jira. One benefit of this is that we
can remove the extra deserialization of those 3 special fields in RequestChannel, which depends
on all requests having those 3 fields in the same order and seems brittle.

> We should fix the correlation ids in every request sent to Kafka and fix the request
log on the broker to specify not only the type of request and who sent it, but also the correlation
id. This will be very helpful while troubleshooting problems in production.
