Ketu - The Kafka Client We Deserve
Using Apache Kafka can be daunting. It requires understanding consumer and producer semantics, managing threads, handling specific exceptions and navigating long yet lacking documentation and complex configuration options. As clojure developers we prefer APIs to be idiomatic, data-driven and friendly yet performant. In this talk I’ll present Ketu, a kafka client built for the CSP/channels style of programming, including design decisions that got us data-driven setup, familiar types, core.async integration, opinionated defaults and extension/substitution points while keeping a keen eye on performance. It’s the Kafka client we truly deserve.
