Jun Rao commented on KAFKA-375:
-------------------------------
Looks good. The only thing is that message format has changed in 0.7.1 slightly
(an optional attribute field) and we need to reflect that in design. Once
that's fixed, we can commit.
/**
* A message. The format of an N byte message is the following:
*
* If magic byte is 0
*
* 1. 1 byte "magic" identifier to allow format changes
*
* 2. 4 byte CRC32 of the payload
*
* 3. N - 5 byte payload
*
* If magic byte is 1
*
* 1. 1 byte "magic" identifier to allow format changes
*
* 2. 1 byte "attributes" identifier to allow annotations on the message
independent of the version (e.g. compression enabled, type of codec used)
*
* 3. 4 byte CRC32 of the payload
*
* 4. N - 6 byte payload
*
