Behavior of Tell vs Notify

[NatElkins]

Hi,

Great project! I am trying to compare the experience of using Orleankka to using Akka.NET. The default messaging pattern in Akka.NET is to use Tell, rather than Ask. I see that in Orleankka, a Tell method is also used. The default behavior of Tell in Akka.NET is to return as soon as the message has been added to the Actor's mailbox. Does Tell have the same behavior in Orleankka? I notice that it returns a task which gets awaited. And how does this differ from Notify?

Here's a recent article I read which may be relevant: https://petabridge.com/blog/actorref-tell-ask/

Thank you!

Tell and Ask are both blocking (in a sense that control flow will return only when the operation is completed by target actor). Notify’s behavior is same as Tell in Akka - ie, fire-n-forget11 груд. 2024 р. о 21:11 Nat Elkins ***@***.***> пише: Hi, Great project!

Got it, thank you for the quick response!

If that is the case, why even have the difference between Ask and Tell? Is it just about signaling whether something will be returned back to the sender or not? Also, the key point of Tell in Akka.NET is that it returns successfully only if the message is added to the target grain's mailbox. According to the docs, OneWay is truly one way.

One-way requests return to the caller immediately and don't signal failure or completion. A one-way request doesn't even guarantee that the callee received the request.
