Yi Pan (Data Infrastructure) commented on SAMZA-855:
----------------------------------------------------

[~rjc...@gmail.com], glad that you want to take it up! Really appreciate it! 

There was an email discussion on the potential compatibility issues. Some of 
Samza community users are still using Kafka 0.8.2 broker versions, which may be 
an issue if Samza's Kafka client version is 0.9 and above. [~cpsoman], could 
you comment on when Uber will be move to Kafka 0.9 and above on the broker side?

One potential way to maintain backward compatibility is to:
# upgrade the default KafkaSystemFactory and corresponding consumer/producers 
to Kafka 0.9
# keep the current KafkaSystemFactory as OldKakfaSystemFactory and rename the 
corresponding consumer/producers to OldKafkaSystemConsumer and 
OldKafkaSystemProducer for users who are not ready to move to newer version of 
Kafka on the broker side

Thoughts?
