Introduction to the Actor Model
summary
Introduces the actor model: actors communicate via message passing, location transparency, and one-in-flight message processing per actor, making them well suited for concurrent, scalable systems and common in MMO games. Demonstrates the model by first modelling an example with threads and then reimplementing it with actors, using examples and benchmarking to compare differences, similarities, pros and cons of threads vs actors.
