Does anyone knows details about the KSQL-engine that computes the queries? According to their git, there can be multiple KSQL-engines in a Client-Server configuration. Is the workload for one query distributed? Is the SQL translated into a program using the Kafka streaming API?

Yes, queries are translated into Kafka Streams API. In the client-server(cluster) mode each query will run on every instance of engine the same way kafka streams apps run on multiple instances.
