This is a simple use case of being a gateway between REST API and Kafka. We can do a lot more than that in NiFi. We can be a Kafka Consumer and Producer as well as POST REST calls and receive any REST calls on configurable ports. All with No Code.

NiFi can act as a listener for HTTP Requests and provide HTTP Responses in a scriptable full Web Server mechanism with JETTY. Or it can listen for HTTP REST calls on a port and route those files anywhere. https://community.cloudera.com/t5/Community-Articles/Parsing-Web-Pages-for-Images-with-Apache-NiFi/ta-p/248415 . We can also do websockets https://community.cloudera.com/t5/Community-Articles/An-Example-WebSocket-Application-in-Apache-NiFi-1-1/ta-p/248598. https://community.cloudera.com/t5/Community-Articles/Accessing-Feeds-from-EtherDelta-on-Trades-Funds-Buys-and/ta-p/248316

It is extremely easy to do this in NiFi.

Kafka Consumer to REST POST

HTTP REST to Kafka Producer
