JIRA: KAFKA-3294 

Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

The goal is to add Kafka Rest Server/Proxy to Kafka Repository. This will allow any language/tool that
can work with HTTP to produce and consume messages, and perform administrative actions with Kafka service.

Why add Kafka Rest Server/Proxy to Kafka?

There are already some open-source REST proxies are available. Some are specific to a particular user cases
Confluent REST Proxy got comprehensive interface. We want to add Kafka Rest Server to Kafka for the following reasons.

1) Many data Infra tools comes up with Rest Interface. It is useful to have inbuilt Rest API support for Produce,
   Consume messages and admin interface for integrating with external management tools.
2) Shipping Kafka Rest Server as part of a normal Kafka release makes it immediately available to every user that downloads Kafka.
3) Helps to maintain the version compatibility between Kafka and Rest Server.
 

Some of the good practices and ideas will be borrowed from existing tools.

Main Reason for this KIP is to add Rest Server to Kafka. Shipping Kafka Rest Server as part of a normal Kafka release
makes it immediately available to every user that downloads Kafka. Also helps to maintain the version compatibility
between Kafka clients and Rest Server.
