rvansa opened a new pull request, #13619: URL: https://github.com/apache/kafka/pull/13619
This change intends to support an application using Vertx GRPC server to perform the Checkpoint and Restore on JVM implementing this, specifically using [OpenJDK CRaC](https://github.com/openjdk/crac/tree/crac) or future versions of OpenJDK. Package org.crac is a facade that either forwards the invocation to actual implementation or provides a no-op implementation. Right now a test of the actual behaviour is not provided; without running on CRaC-enabled JVM there's nothing that would invoke the `Resource` methods, and making this a part of testsuite would be complicated (probably through a containerized test). If needed, I could try to put together a test not involving the actual checkpoint, that would verify that the code does not deadlock and that connections are eventually re-created. It is not entirely clear to me what level of API publicity are the `KafkaClient` and `Selectable` interfaces and in what version could this land, or if I should do the changes only on the implementation classes. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
