Chesnay Schepler updated FLINK-29281: ------------------------------------- Description: Following the license change I propose to eventually replace Akka. Based on LEGAL-619 an exemption is not feasible, and while a fork _may_ be created it's long-term future is up in the air and I'd be uncomfortable with relying on it. I've been experimenting with a new RPC implementation based on gRPC and so far I'm quite optimistic. It's also based on Netty while not requiring as much of a tight coupling as Akka did. This would also allow us to sidestep migrating our current Akka setup from Netty 3 (which is affected by several CVEs) to Akka Artery, both saving work and not introducing an entirely different network stack to the project. was: Following the license change I propose to eventually replace Akka.
