docs.scala-lang VS Apache Kafka

Apple use Scala, not Java, for that sort of thing. At least that was the case last time I interacted with them.

Here are some of the suggested starting points for Scala: https://docs.scala-lang.org/

Here are the Scala books I've written: https://noelwelsh.com/landing/books/

Here's the coding group I run: https://www.scalabridgelondon.org/

ScalaBridge's online events have attendees from across Europe.

Type class is an interesting concept and I have been reading about it from different sources. So, I decided to pen down my learning from different sources like scala-lang.org, scalac.io, with examples that I could relate to better.

First you need to learn idiomatic Scala, start here: https://docs.scala-lang.org

That wording is out of date. I've just submitted https://github.com/scala/docs.scala-lang/pull/2241 to update it.

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.

Source and documentation on GitHub

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!
