I've just browsed through a book "Fast Data Architectures For Streaming Applications" by Dean Wampler and was pleased to notice they reference to Gearpump!
We are in a good company (Flink, Kafka Streams, Akka Streams). They mention Gearpump in context of integration with Beam and Akka Streams. Regards, Karol P.S. I found the doc here: https://info.lightbend.com/COLL-20XX-Fast-Data-Architectures-for-Streaming-Apps_RES-LP-TY.html
