What is CRaC (Coordinated Restore at Checkpoint)? How does it complement native images?
CRaC checkpoints a fully warmed-up, already-JIT-optimized JVM process and restores it almost instantly — unlike Native Image (AOT, no JVM at all), CRaC keeps the real JVM, giving you full JIT performance AND fast startup. Spring Boot 3.2+ supports a Checkpointable lifecycle, aimed at serverless cold-start scenarios.
