Zio-kafka, faster than java-kafka

Concurrency and pre-fetching gives zio-kafka a higher consumer throughput than the default java Kafka client for most workloads.

Debugging a Scala Compilation Issue, a journey into Variance and LUB

At work, I recently encountered a tricky compilation issue. To debug it, I extracted the minimal amount of code necessary to reproduce the problem. After a lot of experimentation, I sought help from a French Scala community. By chance, my colleague Marc came to the rescue. Since this issue might affect others, I’m detailing the journey in this post to help you understand and resolve similar challenges.
