Description

Akka 2.6.x will not receive security fixes from September 2023 onwards (see https://discuss.lightbend.com/t/2-6-x-maintenance-proposal/9949).

A mid-term plan to replace Akka is described in FLINK-29281. In the meantime, we suggest to replace Akka by Apache Pekko (incubating), which is a fork of Akka 2.6.x under the Apache 2.0 license. This way - if needed - we at least have the ability to release security fixes ourselves in collaboration with the Pekko community.
