What is the impact of Kafka Streams on reactive-kafka?

[Axel Poigné]

Seems to me that Kafka streams support distribution but not back pressure, reactive-kafka vice versa.

Anyway, using Kafka streams seems to be very lightweight when using Kafka.

Any comments?

Hi Axel,

I am not sure what the question is about here. Anyway, reactive-kafka is not just about reading from Kafka, it also provides a Reactive Streams based interface that allows interoperability with anything that implements RS.

For reference, Kafka Streams is this thing: http://www.confluent.io/blog/introducing-kafka-streams-stream-processing-made-simple

Reactive Kafka is (or will be) a Kafka connector to/from Akka Streams (and thereby also Reactive Streams).

It looks like Kafka Streams provides another streaming DSL, but I don't know anything about it.

 Hi Patrik, 

i am aware of both. My understanding of Kafka Streams, however, is miniscule. I hoped for some enlightenment by someone more knowledgable if compared to Reactive Kafka. Seems that Kafka Streams have some interesting ideas concerning the dichotomy of event streams and tables.

It looks like Kafka Streams is more of a distributed framework, does balancing, the app can be moved, etc.

RS based streams on the other hand are more lightweight and local. I.e. after reading this article this looks like an apples vs. oranges comparison for now.
