Diving into Kafka Internals with David Jacot

In this video I talk to David Jacot who works as a Staff Software Engineer at  @Confluent  and has been a long time Kafka user, committer and PMC member. We covered how Kafka works internally in great depth. We use Kafka for various use cases and it works great, but going one level below the abstraction and truly understanding the protocols, techniques and algorithms used is a fun ride.
