java-kafka-client VS Apache Kafka

This is particularly useful if you use Apache Kafka in a microservices architecture and you want to add tracing supervision. For example, using OpenTracing you can take a look at opentracing-contrib/java-kafka-client that provides TracingProducerInterceptor and TracingConsumerInterceptor. Those interceptors inject and retrieve span context from record headers.

Apache Kafka — a distributed event streaming platform implementing a variant of the Raft consensus protocol (written in Java, integrated with Scala);

Spring does this during autoconfiguration. For example this and this. When the user adds a configuration then it gets to overwrite the default from the template. I am looking for something similar, perhaps simpler approach.

Code is still in trunk though. https://github.com/apache/kafka/tree/trunk/connect/file/src/main/java/org/apache/kafka/connect/file

I briefly described the algorithm in this article and there is a wonderful article from Kafka that goes into more depth in their general purpose implementation. My implementation is specialized and over optimized in comparison, e.g. by using bit manipulation to avoid more expensive division/modulus instructions. Tokio rewrote their timerwheel after I showed them mine, borrowing some ideas but also staying more general. Hope that helps!
