Akka.NET v1.4.28

1.4.28 November 10 2021

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:

Akka.NET v1.4.27

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
ProcessorCount:                    16
ClockSpeed:                        0 MHZ
Actor Count:                       32
Messages sent/received per client: 200000  (2e5)
Is Server GC:                      True
Thread count:                      111

Num clients, Total [msg], Msgs/sec, Total [ms]
         1,  200000,    130634,    1531.54
         5, 1000000,    246975,    4049.20
        10, 2000000,    244499,    8180.16
        15, 3000000,    244978,   12246.39
        20, 4000000,    245159,   16316.37
        25, 5000000,    243333,   20548.09
        30, 6000000,    241644,   24830.55

In Akka.NET v1.4.27 those numbers now look like:

OSVersion:                         Microsoft Windows NT 6.2.9200.
ProcessorCount:                    16                            
ClockSpeed:                        0 MHZ                         
Actor Count:                       32                            
Messages sent/received per client: 200000  (2e5)                 
Is Server GC:                      True                          
Thread count:                      111                           
                                                                 
Num clients, Total [msg], Msgs/sec, Total [ms]                   
         1,  200000,    105043,    1904.29                       
         5, 1000000,    255494,    3914.73                       
        10, 2000000,    291843,    6853.30                       
        15, 3000000,    291291,   10299.75                       
        20, 4000000,    286513,   13961.68                       
        25, 5000000,    292569,   17090.64                       
        30, 6000000,    281492,   21315.35

To put these numbers in comparison, here's what Akka.NET's performance looked like as of v1.4.0:

Num clients (actors)    Total [msg] Msgs/sec    Total [ms]
1   200000  69736   2868.60
5   1000000 141243  7080.98
10  2000000 136771  14623.27
15  3000000 38190   78556.49
20  4000000 32401   123454.60
25  5000000 33341   149967.08
30  6000000 126093  47584.92

We've made Akka.Remote consistently faster, more predictable, and reduced total memory consumption significantly in the process.

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.

Bug Fixes and Improvements

Performance Improvements
Using our standard RemotePingPong benchmark, the difference between v1.4.24 and v1.4.25 is significant:

        30, 6000000,    241644,   24830.55

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.

Akka.NET v1.4.23

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.

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

Maintenance Release for Akka.NET 1.4

Akka.NET v1.4.21 is a significant release that includes major performance improvements, bug fixes, and a major update to the Akka.DependencyInjection NuGet package.

N.B. these after numbers don't benefit from the performance benefits we observed in v1.4.20 when we invoked ThreadPool.SetMinThreads(0,0), which makes them even more impressive.

Akka.DependencyInjection Updates
We had one major issue we implemented in v1.4.21 for Akka.DependencyInjection: Abstraction of ServiceProvider, Improving Akka.DependencyInjection

What this change did was:

  • Deprecate the Akka.DependencyInjection.ServiceProvider class in favor of the Akka.DependencyInjection.DependencyResolver class - to avoid namespace collision with Microsoft.Extensions.DependencyInjection.ServiceProvider;
  • Deprecates the Akka.DependencyInjection.ServiceProviderSetup class in favor of the Akka.DependencyInjection.DependencyResolverSetup class for consistency reasons;
  • Akka.DependencyInjection.DependencyResolver now takes an input of type IDependencyResolver, which allows users to abstract away the IServiceProvider and mock / replace it during unit testing; and
  • Added some non-generic Props methods for dynamically spawning actors via DI.

All of these changes are backwards-compatible with v1.4.20 and earlier - and the deprecation warnings will appear in your code when you upgrade. If you run into any issues upgrading to Akka.DependencyInjection v1.4.21 please reply on this thread!
