I'm finishing up an application that's built around a Kafka Streams topology. Kafka Streams is quite nice and I am excited to put it into production to see how it works. All mutations run through the Kafka Streams application. A Relay webapp client communicates with a graphql-java server which resolves GraphQL queries against a gRPC service layer. This service layer either queries Kafka Streams state stores, other state stores, or writes mutations to Kafka, wherein they are processed by the Kafka Streams topology. Another Kafka Streams topology indexes topics to Elasticsearch. Having separate topologies seems to make it easier to reset them independently in case I want to replay state. All of this is glued together with Protocol Buffers, which are a great complement to both Kafka and Elasticsearch. It is really nice to see Redis join this scene and to see more people getting excited about building applications this way. Looking forward to checking this out.
