Messaging Patterns

Actors communicate by exchanging messages. Proto.Actor supports several common patterns that build on this simple foundation.

• Send – fire and forget, the sender does not expect a reply.
• Ask Pattern – request–response using Request or RequestAsync.
• Envelope Pattern – batch multiple messages and acknowledge them as a unit.
• Routing – use Routers to distribute work across actors or forward messages.

The diagram below summarizes how messages can be routed and queued.
