Consumer api 0.10 backwards compatible with Kafka 0.8

Hello. We are running kafka server 0.8. We are considering upgrading to the
latest version of kafka. Does latest consumer 0.10 backward compatible with
older version of Kafka? What is the right approach of upgrading Kafka
servers and consumers?

Thanks in advance.

I believe there were some incompatibilities between 0.8.x and 0.9.x for 
the clients.

If you are upgrading from 0.8.x to 0.10.x, you should check out the 
upgrade guide available here:
http://kafka.apache.org/documentation.html#upgrade_10

Cheers,
Francis

Hi Vadim,

You have to upgrade the brokers first and then the clients. So, you can use
0.8 clients with 0.10 brokers, but _not_ 0.10 clients with 0.8 brokers.
