Subject Re: Questions reg. Kafka apis and proxy
Date Wed, 09 Dec 2015 17:07:46 GMT

The Java producer APIs has been running in some production environment and
is considered stable; the Java consumer APIs in 0.9 is considered beta and
may have light modifications in the future.

About the metadata-broker-list: this config is only needed to bootstrap the
client, hence does not necessarily need to include all the broker hosts,
for example in practice people could set metadata-broker-list as the
address of a load balancer in front of the Kafka brokers that will be
forwarded, and once the client is up and running it can automatically fetch
the full broker list from a metadata request.
