Hi, Thank you for providing comparison between Samza and Spark Streaming, Mupd8, Storm. Looks like there is new player in the field : Kafka Streams ( https://docs.confluent.io/current/streams/index.html).
It will good to have comparison between Samza and Kafka Streams as well. >From high-level it looks like "Samza when used as a library" is similar to "Kafka Streams". Thanks, Giridhar.
