Hi Kafkateers!
Just wanted to share with you my cheatsheet: GitHub - ZZa/kafka-cheat-sheet: Kafka, Kafka Connect and Schema Registry commands cheat sheet
It covers Kafka, Kafka Connect and Schema Registry most common commands and use-cases. There are also useful links to configuration references in each chapter.
Also, feel free to extend on the list, if you see that something is missing there. What about your favourite and most useful ksqlDB queies?
Br,
Denis
