For Spring Batch applications, Native Images are a game-changer.

1. Instantaneous startup: From 4 seconds to 0.2 seconds.
2. Perfect for batch jobs: Jobs that start, process, and exit benefit the most.
3. Lower memory usage: No JVM, no warm-up, no extra overhead.

By using GraalVM Native Image, you can build batch jobs that are fast, efficient, and perfectly suited for cloud environments where "scale to zero" is essential.

If you're dealing with micro-batch jobs that run for seconds, Native Image is a must-have. If your batch jobs are long-lived (running for hours), the benefit is less significant, but for fast, one-shot batch jobs, Native Image is unbeatable.
