Knowledge on how to use advanced features for this framework to solve cases where standard API do not have required built-in functionality

Apache Kafka-Streams and Apache Kafka-Client APIs: big expertise and deep knowledge of theirs internals, which help with troubleshooting complex cases of failing applications in production. Currently these APIs are the only APIs that has declared support exactly once delivery semantics for Kafka to Kafka data processing applications (important for correct computation of metrics on the platform).
