Cross-platform actors for .NET and Go

Actor Model

The Actor Model provides a higher level of abstraction for writing concurrent and distributed systems. It alleviates the developer from having to deal with explicit locking and thread management, making it easier to write correct concurrent and parallel systems.

Grains / Virtual Actors

Grain abstraction, which provides a straightforward approach to building distributed interactive applications, without the need to learn complex programming patterns for handling concurrency, fault tolerance, and resource management.

Stream Processing

Proto.Actor is designed to optimize for locality, grains can gradually migrate to cluster members from where it receives the most interactions. This allows Proto.Actor to leverage in-process performance for realtime stream processing.

Digital Twins

A digital twin is a virtual representation that serves as the real-time digital counterpart of a physical object or process. By leveraging Proto.Actors local affinity strategy, digital twins can react on external events in realtime.

Metrics and Tracing

Observability is an essential feature for distributed systems. Every area of Proto.Actor has been instrumented to allow users to extract runtime and performance metrics.
Dashboards for DataDog and Grafana are provided out of the box.
