The Akka family of projects is managed by teams at Lightbend with help from the community.
Akka Projections provides an abstraction for consuming a stream of Envelope (where Envelope contains a payload and a trackable offset). This streams can originate from persisted events, Kafka topics, or other Alpakka connectors.
Akka Projections also provides tools to track, restart and distribute these projections.
