Is CRaC in Spring Boot the Future of Java Frameworks?

The Java ecosystem is buzzing with the potential of Coordinated Restore at Checkpoint (CRaC) in Spring Boot. If implemented effectively, CRaC could revolutionize how we handle JVM startup times and resource efficiency—traditionally areas where frameworks like Micronaut and Quarkus have shined. CRaC allows applications to save their state at a checkpoint and restore it instantly, bypassing the slow startup and warm-up phases. Imagine deploying Spring Boot apps that start in milliseconds, rivaling the performance of native-image-based frameworks. This could make the need for Micronaut or Quarkus redundant for many use cases.

Why is this a big deal?

✅ Faster startups: Near-instant application boot times. ✅ Resource efficiency: Reduced memory and CPU overhead. ✅ Seamless integration: Leverage Spring’s rich ecosystem without compromise. While CRaC is still evolving, its potential to level the playing field is undeniable. Could this be the end of the “framework wars”? Only time will tell, but one thing’s clear: Spring Boot is not backing down. What’s your take? Will CRaC make Micronaut and Quarkus obsolete, or will they evolve to stay ahead? Let’s discuss! 💬
