Yeah, that is true. I thought I documented that, but looking at the
protocol docs, it looks like I didn't.
I agree this is kind of a pain in the ass. It was an important
optimization in 0.7 because we didn't know where the message
boundaries were but in 0.8 we have a fast way to compute message
boundaries and in fact we normally don't give out partial messages, I
think this happens when you hit the size threshold of your fetch
request (e.g. 1MB) instead of searching for the nearest message
boundary we give you that chunk of log. I think we should consider
just fixing it entirely in the next release--the perf hit is pretty
minor and it is an annoyance and source of bugs for clients.
For now you have to handle it, so I added documentation to the protocol wiki.
