Akka.NET

Akka.NET logo

Akka.NET is a .NET port of the popular Akka project from the Scala / Java community. We are an idiomatic .NET implementation of the actor model built on top of the .NET Common Language Runtime.

How is Akka.NET Used?

Akka.NET can be used in-process or inside large, distributed real-time systems; we support a wide variety of use cases.

Akka.NET can be used to solve the following types of problems:

Concurrency - Akka.NET actors only process messages one-at-a-time and they do so in first in, first out (FIFO) order; this means that any application state internal to an actor is automatically thread-safe without having to use locks or any other shared-memory synchronization mechanisms.
Stream Processing - Akka.NET actors and Akka.Streams make it easy to build streaming applications, used for processing incoming streams of data or incoming streams of live events such as UI or network events inside native applications.
Event-Driven Programming - actors make it easy to build event-driven applications, as actors' message-processing routines naturally express these types of designs.
Event Sourcing and CQRS - Akka.Persistence, used by actors to make their state re-entrant and recoverable across restarts or migrations between nodes, natively supports event sourcing. Akka.Persistence.Query can be used to compute CQRS-style projections and materialized views from Akka.Persistence data.
Location Transparency - Akka.Remote makes it simple for actors in remote processes to transparently communicate with each other.
Highly Available, Fault-Tolerant Distributed Systems - Akka.Cluster, Akka.Cluster.Sharding, and other tools built on top of Akka.Cluster make it possible to build highly available and fault-tolerant distributed systems by leveraging peer-to-peer programming models with topology-aware message routing and distribution.
Low Latency, High Throughput - Akka.NET aims to be low latency and high throughput, processing 10s millions of messages per second in-memory and hundreds of thousands of messages per second over remote connections.

Where Can I Learn Akka.NET?

You can start by taking the Akka.NET Bootcamp, but there are many other great learning resources for Akka.NET Online.

Install Akka.NET via NuGet

If you want to include Akka.NET in your project, you can install it directly from NuGet

To install Akka.NET Distributed Actor Framework, run the following command in the Package Manager Console

PM> Install-Package Akka.Hosting

Akka.Hosting includes the base Akka NuGet package and also provides an easy interface to integrate Akka.NET with the most-used parts of the Microsoft.Extensions ecosystem: Configuration, Logging, Hosting, and DependencyInjection. We encourage developers to adopt it.

And if you need F# support:

PM> Install-Package Akka.FSharp

Akka.NET Project Templates

To create your own Akka.NET projects using our templates (Akka.Templates), install them via the dotnet CLI:

dotnet new install "Akka.Templates::*"

This will make our templates available via dotnet new on the CLI and as new project templates inside any .NET IDE such as Visual Studio or JetBrains Rider. You can view the full list of templates included in our package here: https://github.com/akkadotnet/akkadotnet-templates#available-templates

Akka.NET v1.5.31 is a maintenance release that addresses several bugs and added new features.
[Persistence: Add logging for failed DeleteAsync() that was caused by failed SaveSnapshot()](https://github.com/akkadotnet/akka.net/pull/7360)
[Persistence: Fix RecoveryTick timer leak](https://github.com/akkadotnet/akka.net/pull/7343)
[Serialization.Hyperion: Fix serializer config bug](https://github.com/akkadotnet/akka.net/pull/7364)
[Sharding: Fix potential `ArgumentException` during shard re-balancing](https://github.com/akkadotnet/akka.net/pull/7367)
[Cluster: Fix multiple `Member` with the same `Address` crashing `ClusterDaemon`](https://github.com/akkadotnet/akka.net/pull/7371)
[Core: Fix `Stash` filtering out identical `Envelope`s](https://github.com/akkadotnet/akka.net/pull/7375)
[Streams: Fix `ShellRegistered` message deadletter log](https://github.com/akkadotnet/akka.net/pull/7376)
[Sharding: Make lease release in `Shard.PostStop` be blocking instead of using detached async task](https://github.com/akkadotnet/akka.net/pull/7383)
[Cluster.Tools: Add missing singleton detection feature for easier infrastructure debugging](https://github.com/akkadotnet/akka.net/pull/7363)
Upgrade Advisory**
There is a slight change in how actor `Stash` behavior. In previous behavior, `Stash` will filter out any messages that are identical (see explanation below) when it is prepended with another. It will not do so now, which is the actual intended behavior.
This change will affect `Akka.Persistence` users or users who use the `Stash.Prepend()` method in their code. You will need to add a de-duplication code if your code depends on sending identical messages multiple times to a persistence actor while it is recovering.
Messages are considered as identical if they are sent from the same sender actor and have a payload message that `Equals()` to true against another message. Example payload types would be an object pointing to the same memory address (`ReferenceEquals()` returns true), value types (enum, primitives, structs), and classes that implements the `IEquatable` interface.
