Introducing Spring for Apache Pulsar
summary
Spring for Apache Pulsar provides auto‑configured Java clients for both the imperative Pulsar client and a reactive client donated by DataStax, plus PulsarTemplate/PulsarListener abstractions, JSON schema defaults, and a spring Cloud stream binder that maps POJO functions to topics. Demo builds a user‑registration pipeline (user -> registeredUser topics) using Gradle, Spring Boot 3 / Spring Framework 6 and Reactor; GraalVM native image cuts startup from ~1.8s to ~0.2s. Planned work adds XA/transaction support and tighter YAML defaults.
