Coordinated Restore at Checkpoint: Quick Start for OpenJDK
summary
Coordinated Restore at Checkpoint is an OpenJDK project that aims to start Java applications in tens of milliseconds by restoring from a checkpoint; it is an alternative to GraalVM Native Image and avoids Native Image’s specific limitations while introducing its own trade-offs. The talk covers the project's active development status and is targeted at people interested in experimental Java startup technologies and framework/application developers who care about startup and warm-up time.
