Session Abstract:

Two years ago, we helped to contribute a framework for exactly once semantics (or EOS) to Apache Kafka. This much-needed feature brought transactional guarantees to stream processing engines such as Kafka Streams. In this talk, we will recount the journey since then and the lessons we have learned as usage has gradually picked up steam. What did we get right and what did we get wrong? Most importantly, we will discuss how the work is continuing to evolve in order to provide more reliability and better performance. This talk assumes basic familiarity with Kafka and the log abstraction. What you will get out of it is a deeper understanding of the underlying architecture of the EOS framework in Kafka, what its limitations are, and how you can use it to solve problems.
