Gregoire Seux updated KAFKA-436:
--------------------------------

    Description: 
Fetchsize parameter is per partition in fetch requests. 
This makes the size of response unpredicatable and thus might overflow.

(original email : http://mail-archives.apache.org/mod_mbox/incubator-kafka-users/201208.mbox/%3C416A89FBBC95114F8B2D2E91781541E9638B201E%40SRVEX02.criteois.lan%3E   )

Two propositions : 
- fetch size is only a hint, broker will ensure that it w'ont overflow (maybe not sending too much data)
- broker respect fetchsize as a global limit and not by partition
