Akka.FSharp vs Akkling: features
Akka.FSharp Akkling
Idiomatic Akka.NET F# API:
• Defining actors
• Changing actor state (using
mutually recursive F# functions to
implement Become/Unbecome)
• Defining persistent actors (clumsy
API making persistent actors look
very different and hard to
customize)
Idiomatic Akka.NET F# API:
• Defining actors (almost like in
officialAPI, but typed)
• Changing actor state like in offical
API
• Redesigned persistent actors
• Lifecycle event
• Cluster sharding
• Distributed data
• Akka Streams

let mkActor =
spawn system "MyActor"
<| fun mailbox ->
let rec loop () = actor {
let! message = mailbox.Receive()
match message with
| Greet(name) -> printfn "Hello %s" name
| Hi -> printfn "Hello from F#!"
return! loop ()
}
loop ()
