Hey folks,
I have a question regarding potential performance impacts of running
Samza against newer Kafka brokers. We have languished on the old on-
disk message  format for Kafka for some time, and want to upgrade to
the newer format which supports timestamps. Samza currently accounts
for quite a bit of our message consumption and I am concerned that it
will cause a broker performance hit due to downconversion of messages.
I know Samza uses the old SimpleConsumer internally which does not
support the newer format. Has Samza been tested against newer broker
versions using the new message format, and if so does it have a
significant performance impact? Are their plans to move Samza to the
new consumer?
