Help me identify this design pattern
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.

What is Kafka ?
Source and documentation on GitHub

A simple file source/sink connector?
Code is still in trunk though. https://github.com/apache/kafka/tree/trunk/connect/file/src/main/java/org/apache/kafka/connect/file

Can someone please eli5 how the hierarchical timing wheel algorithm works?
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!

Got fed up with AMQP, so I wrote a HTTP message broker on top of RabbitMQ
Let's draw some parallels in the Kafka ecosystem, in which there are Confluent REST Proxy and Hermes by Allegro. You could say that since Kafka uses a binary protocol over TCP, both of these projects are "moot and useless". Despite that, Allegro aka the Poland's Amazon still maintains that project and uses it in production as a means of HTTP-based communication between their 700+ microservices arguing that it makes their development process easier, since it allows them to abstract away the intricacies of Kafka and use plain HTTP instead.
