Apache Kafka has been the go-to publish-subscribe (pub-sub) messaging system for a while. It offers functionality for a wide range of enterprise use cases, along with a large ecosystem of tools and a dedicated community. But lately, upstart Apache Pulsar has been gaining ground. Pulsar takes the best parts of Kafka and expands on them to solve problems that were out of the scope of Kafka’s original design but which are lately coming to Kafka.
In this session, we'll cover the differences between them, how to choose one depending on your use case, and the state of the art of both.
