1.5.7 May 17th 2023

Akka.NET v1.5.7 is a significant release that introduces a major new reliable message delivery feature to Akka.NET and Akka.Cluster.Sharding: Akka.Delivery.

Akka.Delivery

Akka.Delivery is a reliable delivery system that leverages built-in actors, serialization, and persistence to help guarantee that all messages sent from one producer to one consumer will be delivered, in-order, even across process restarts / actor restarts / network outages.

Akka.Delivery's functionality is divded across four libraries:

  • Akka - defines the base definitions for all messages, the ProducerController type, and the ConsumerController type;
  • Akka.Cluster - contains the serialization definitions for Akka.Delivery;
  • Akka.Persistence - contains the EventSourcedProducerQueue implementation, an optional feature that can be used to make the ProducerController's outbound delivery queue persisted to the Akka.Persistence Journal and SnapshotStore; and
  • Akka.Cluster.Sharding - contains the definitions for the ShardingProducerController and ShardingConsumerController.

We've documented how these features work in the following two detailed articles official website:

1.5.3 April 20th 2023

SQL Transaction Isolation Level Setting

In 1.5.3, we're introducing fine-grained control over transaction isolation level inside the Akka.Persistence.Sql.Common common library. This setting will be propagated to the rest of the SQL persistence plugin ecosystem and the Akka.Hosting package in their next release version.

Four new HOCON settings are introduced:

  • akka.persistence.journal.{plugin-name}.read-isolation-level
  • akka.persistence.journal.{plugin-name}.write-isolation-level
  • akka.persistence.snapshot-store.{plugin-name}.read-isolation-level
  • akka.persistence.snapshot-store.{plugin-name}.write-isolation-level

you can go to the official Microsoft documentation to read more about these isolation level settings.

1.5.0-beta1 February 20th 2023

Version 1.5.0-beta1 contains breaking API changes and new API changes for Akka.NET.

Breaking Changes: Logging

In #6408 the entire ILoggingAdapter interface was rewritten in order to improve extensibility and performance (logging is now 30-40% faster in all cases and allocates ~50% fewer objects for large format strings).

All of the changes made here are source compatible, but not binary compatible - meaning that users and package authors will need to do the following:

  • Add using Akka.Event in all files that used the ILoggingAdapter and
  • Recompile.

NOTE: you can use a global using Akka.Event directive to do this solution / project-wide if your project supports C# 10 and / or .NET 6.

In addition to improving the performance of the ILoggingAdapter system, we've also made it more extensible - for instance, you can now globally configure the ILogMessageFormatter via the following HOCON:

akka { 
    loglevel=INFO,
    loggers=["Akka.Logger.Serilog.SerilogLogger, Akka.Logger.Serilog"]
    logger-formatter="Akka.Logger.Serilog.SerilogLogMessageFormatter, Akka.Logger.Serilog"
}

That will allow users to use the SerilogLogMessageFormatter globally throughout their applications - no more annoying calls like this inside individual actors that want to use semantic logging:

private readonly ILoggingAdapter _logger = Context.GetLogger<SerilogLoggingAdapter>();

Breaking Changes: Akka.Persistence.Sql.Common

This is a breaking change that should effect almost no users, but we deleted some old, bad ideas from the API surface and it might require all Akka.Persistence.Sql* plugins to be recompiled.

For what it's worth, Akka.Persistence.Sql.Common's performance has been improved significantly and we'll continue working on that with some additional API changes this week.

1.5.0-alpha3 November 15th 2022

Akka.NET v1.5.0-alpha3 is a security patch for Akka.NET v1.5.0-alpha2 but also includes some other fixes.

Security Advisory: Akka.NET v1.5.0-alpha2 and earlier depend on an old System.Configuration.ConfigurationManager version 4.7.0 which transitively depends on System.Common.Drawing v4.7.0. The System.Common.Drawing v4.7.0 is affected by a remote code execution vulnerability GHSA-ghhp-997w-qr28.

We have separately created a security advisory for Akka.NET Versions < 1.4.46 and < 1.5.0-alpha3 to track this issue.

Fixes and Updates

You can see the full set of tracked issues for Akka.NET v1.5.0 here.

1.5.0-alpha2 October 17th 2022

Akka.NET v1.5.0-alpha2 is a maintenance release for Akka.NET v1.5 that contains numerous performance improvements in critical areas, including core actor message processing and Akka.Remote.

Performance Fixes

In sum you should expect to see total memory consumption, garbage collection, and throughput improve when you upgrade to Akka.NET v1.5.0-alpha2.

Other Features and Improvements

1.5.0-alpha1 August 22 2022

Akka.NET v1.5.0-alpha1 is a major release that contains a lot of code improvement and rewrites/refactors. Major upgrades to Akka.Cluster.Sharding in particular.

Deprecation

Some codes and packages are being deprecated in v1.5

Changes

Akka

Akka.Cluster

Akka.Cluster.Sharding

The Akka.Cluster.Sharding changes in Akka.NET v1.5 are significant, but backwards compatible with v1.4 and upgrades should happen seamlessly.

Akka.Cluster.Sharding's state-store-mode has been split into two parts:

  • CoordinatorStore
  • ShardStore

Which can use different persistent mode configured via akka.cluster.sharding.state-store-mode & akka.cluster.sharding.remember-entities-store.

Possible combinations:

state-store-mode remember-entities-store CoordinatorStore mode ShardStore mode
persistence (default) - (ignored) persistence persistence
ddata ddata ddata ddata
ddata eventsourced (new) ddata persistence

There should be no breaking changes from user perspective. Only some internal messages/objects were moved.
There should be no change in the PersistentId behavior and default persistent configuration (akka.cluster.sharding.state-store-mode)

This change is designed to speed up the performance of Akka.Cluster.Sharding coordinator recovery by moving remember-entities recovery into separate actors - this also solves major performance problems with the ddata recovery mode overall.

The recommended settings for maximum ease-of-use for Akka.Cluster.Sharding going forward will be:

akka.cluster.sharding{
  state-store-mode = ddata
  remember-entities-store = eventsourced
}

However, for the sake of backwards compatibility the Akka.Cluster.Sharding defaults have been left as-is:

akka.cluster.sharding{
  state-store-mode = persistence
  # remember-entities-store (not set - also uses legacy Akka.Persistence)
}

Switching over to using remember-entities-store = eventsourced will cause an initial migration of data from the ShardCoordinator's journal into separate event journals going forward - this migration is irreversible without taking the cluster offline and deleting all Akka.Cluster.Sharding-related data from Akka.Persistence, so plan accordingly.

1.4.32 January 19 2022

Akka.NET v1.4.32 is a minor release that contains some API improvements. Most of the changes have been aimed at improving our web documentation and code cleanup to modernize some of our code. One big improvement in this version release is the Hyperion serialization update.

Hyperion 0.12.0 introduces a new deserialization security mechanism to allow users to selectively filter allowed types during deserialization to prevent deserialization of untrusted data described here. This new feature is exposed in Akka.NET in HOCON through the new akka.actor.serialization-settings.hyperion.allowed-types settings or programmatically through the new WithTypeFilter method in the HyperionSerializerSetup class.

The simplest way to programmatically describe the type filter is to use the convenience class TypeFilterBuilder:

var typeFilter = TypeFilterBuilder.Create()
    .Include<AllowedClassA>()
    .Include<AllowedClassB>()
    .Build();
var setup = HyperionSerializerSetup.Default
    .WithTypeFilter(typeFilter);

You can also create your own implementation of ITypeFilter and pass an instance of it into the WithTypeFilter method.

For complete documentation, please read the Hyperion readme on filtering types for secure deserialization.

Maintenance Release for Akka.NET 1.4
Akka.NET v1.4.28 is a minor release that contains some enhancements for Akka.Streams and some bug fixes.

New Akka.Streams Stages
Akka.NET v1.4.28 includes two new Akka.Streams stages:

  • Source.Never - a utility stage that never emits any elements, never completes, and never fails. Designed primarily for unit testing.
  • Flow.WireTap - the WireTap stage attaches a given Sink to a Flow without affecting any of the upstream or downstream elements. This stage is designed for performance monitoring and instrumentation of Akka.Streams graphs.

In addition to these, here are some other changes introduced Akka.NET v1.4.28:

1.4.27 October 11 2021

Maintenance Release for Akka.NET 1.4
Akka.NET v1.4.27 is a small release that contains some major performance improvements for Akka.Remote.

Performance Fixes
In RemoteActorRefProvider address paring, caching and resolving improvements Akka.NET contributor @Zetanova introduced some major changes that make the entire ActorPath class much more reusable and more parse-efficient.

Our last major round of Akka.NET performance improvements in Akka.NET v1.4.25 produced the following:

OSVersion:                         Microsoft Windows NT 6.2.9200.0

1.4.25 September 08 2021

Maintenance Release for Akka.NET 1.4
Akka.NET v1.4.25 includes some significant performance improvements for Akka.Remote and a number of important bug fixes and improvements.

This represents a 24% overall throughput improvement in Akka.Remote across the board. We have additional PRs staged that should get aggregate performance improvements above 40% for Akka.Remote over v1.4.24 but they didn't make it into the Akka.NET v1.4.25 release.

1.4.23 August 09 2021

Maintenance Release for Akka.NET 1.4

Akka.NET v1.4.23 is designed to patch an issue that occurs on Linux machines using Akka.Cluster.Sharding with akka.cluster.sharding.state-store-mode=ddata and akka.cluster.sharding.remember-entities=on: "System.DllNotFoundException: Unable to load shared library 'lmdb' or one of its dependencies"

In Akka.NET v1.4.21 we added built-in support for Akka.DistributedData.LightningDb for use with the remember-entities setting, but we never received any reports about this issue until shortly after v1.4.22 was released. Fundamentally, the problem was that our downstream dependency, Lightning.NET, doesn't include any of the necessary Linux native binaries in their distributions currently. So in the meantime, we've published our own "vendored" distribution of Lightning.NET to NuGet until a new official one is released that includes these binaries.

There are some other small fixes included in Akka.NET v1.4.23 and you can read about them here.

1.4.22 August 05 2021

Maintenance Release for Akka.NET 1.4

Akka.NET v1.4.22 is a fairly large release that includes an assortment of performance and bug fixes.

Performance Fixes
Akka.NET v1.4.22 includes a significant performance improvement for Ask<T>, which now requires 1 internal await operation instead of 3:

Akka.Cluster.Sharding.RepairTool
In addition to the work done on Akka.NET itself, we've also created a separate tool for cleaning up any left-over data in the event of an Akka.Cluster.Sharding cluster running with akka.cluster.sharding.state-store-mode=persistence was terminated abruptly before it had a chance to cleanup.

We've added documentation to the Akka.NET website that explains how to use this tool here: https://getakka.net/articles/clustering/cluster-sharding.html#cleaning-up-akkapersistence-shard-state

And the tool itself has documentation here: https://github.com/petabridge/Akka.Cluster.Sharding.RepairTool
