One year with Akka 2.6
summary
Akka 2.6 makes the typed actor API the default (released Nov 2019) and becomes the base for new features: PersistenceTyped offers event‑sourcing primitives and explicit command/event/reply types; Cluster Sharding adds an external shard allocation hook used with Alpakka Kafka to co‑locate Kafka partitions and cut inter‑node hops; a new remoting layer optimizes peer‑to‑peer connections; Projections implements read‑side pipelines with at‑least‑once / at‑most‑once (and transactional “exactly once” with JDBC) semantics; the Split Brain Resolver is now open source with a Kubernetes lease strategy.
