David Ormsbee updated KAFKA-223:

>                 Key: KAFKA-223
>                 URL:
>             Project: Kafka
>          Issue Type: Improvement
>          Components: clients, core

> It would be useful to be able to query metadata from Kafka for the purposes of monitoring
and discovery:
> 1. Version: Just a quick way to get the broker version so that we know not to send it
a version of a request or response that it can't handle.
> 2. Topic information: Return the default number of partitions per topic, a list of all
topics, number of partitions per topic if there are overrides, and start/end offsets for those
topics (assuming it's cheap to do so). This would allow Consumers and Producers to discover
topics and partitions on a single broker without involving ZooKeeper, and would also make
it easier to know how many partitions can be sent to when making a new topic with a ZK-aware
