What's new in Spring Batch 5
summary
Spring Batch 5 raises the baseline to Java 17 baseline and integrates Spring Framework 6, Micrometer 1.10 and new DB support (SAP HANA, MariaDB as first‑class), moves execution context serialization to execution context now Base64, adds proper Java record support with automatic reader/writer mapper selection, replaces old job‑param syntax with a key=value[,type[,id]] and any‑type conversion via Spring ConversionService, exposes tracing (Zipkin/OpenTelemetry) and metrics, and makes GraalVM native builds practical with GraalVM native: 20–30× startup speed and ~2× runtime speed on a 1M‑item benchmark; expect DB DDL changes and removed legacy stores.
