Spring Batch Performance Tuning
summary
Refactors a single‑threaded Spring Batch job that resizes ~5,000 images into Concurrent Steps, AsyncItemProcessor/AsyncItemWriter, Remote Chunking and Remote Partitioning, showing measured runs: single‑thread ~2m49s, multi‑thread ~43–46s, async ~49s, remote chunking ~1m2s using multiple slave processes over JMS (ActiveMQ) in demos. Uses Spring Batch 3.x (JSR‑352 support), Spring Integration for messaging, and deploys jobs to Spring XD for high availability, showing the distributed builds actually run and report back to the job repository.
