-----------------------------------
{quote}Seems like javabin can be quite easily used to send messages to overseer
using the work queues, and then have overseer compute the final cluster state
as JSON.

Yes, that was added to support both json and javabin
bq.The messages to the overseer are usually very small, I don't think the gain
will be that much (speed or size)....
Well, the messages are small. But the no:of messages we process are sometimes
1000s every second for a very large cluster. My own benchmark shows that even
for small messages it can be 20% to 30% in encoding decoding. I'm in the
process of making a lot many more improvements to javabin encoding/decoding
and that can make the perf improvements even more significant.
This is a micro optimization. Not very essential and it is not very urgent
> Use javabin instead of JSON to send messages to overseer
