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
[Deprecated/removed Akka.DI package](https://github.com/akkadotnet/akka.net/pull/6003)
Please use the new `Akka.DependencyInjection` NuGet package as a replacement. Documentation can be read [here](https://getakka.net/articles/actors/dependency-injection.html)
[Deprecated/removed Akka.MultiNodeTestRunner package](https://github.com/akkadotnet/akka.net/pull/6002)
Please use the new `Akka.MultiNode.TestAdapter` NuGet package as a replacement. Documentation can be read [here](https://getakka.net/articles/testing/multi-node-testing.html).
[Streams] [Refactor `SetHandler(Inlet, Outlet, IanAndOutGraphStageLogic)` to `SetHandlers()`](https://github.com/akkadotnet/akka.net/pull/5931)
__Changes__
__Akka__
[Add dual targetting to support .NET 6.0](https://github.com/akkadotnet/akka.net/pull/5926)
All `Akka.NET` packages are now dual targetting netstandard2.0 and net6.0 platforms, we will be integrating .NET 6.0 better performing API and SDK in the future.
[Add `IThreadPoolWorkItem` support to `ThreadPoolDispatcher`](https://github.com/akkadotnet/akka.net/pull/5943)
[Add `ValueTask` support to `PipeTo` extensions](https://github.com/akkadotnet/akka.net/pull/6025)
[Add `CancellationToken` support to `Cancelable`](https://github.com/akkadotnet/akka.net/pull/6032)
[Fix long starting loggers crashing `ActorSystem` startup](https://github.com/akkadotnet/akka.net/pull/6053)
All loggers are asynchronously started during `ActorSystem` startup. A warning will be logged if a logger does not respond within the prescribed `akka.logger-startup-timeout` period and will be awaited upon in a detached task until the `ActorSystem` is shut down. This have a side effect in that slow starting loggers might not be able to capture all log events emmited by the `EventBus` until it is ready.
__Akka.Cluster__
[Fix `ChannelTaskScheduler` to work with Akka.Cluster, ported from 1.4](https://github.com/akkadotnet/akka.net/pull/5920)
[Harden `Cluster.JoinAsync()` and `Cluster.JoinSeedNodesAsync()` methods](https://github.com/akkadotnet/akka.net/pull/6033)
[Fix `ShardedDaemonProcess` should use lease, if configured](https://github.com/akkadotnet/akka.net/pull/6058)
[Make `SplitBrainResolver` more tolerant to invalid node records](https://github.com/akkadotnet/akka.net/pull/6064)
[Enable `Heartbeat` and `HearbeatRsp` message serialization and deserialization](https://github.com/akkadotnet/akka.net/pull/6063)
By default, `Akka.Cluster` will now use the new `Heartbeat` and `HartbeatRsp` message serialization/deserialization that was introduced in version 1.4.19. If you're doing a rolling upgrade from a version older than 1.4.19, you will need to set `akka.cluster.use-legacy-heartbeat-message` to true.
__Akka.Cluster.Sharding__
[Make Cluster.Sharding recovery more tolerant against corrupted persistence data](https://github.com/akkadotnet/akka.net/pull/5978)
[Major reorganization to Akka.Cluster.Sharding](https://github.com/akkadotnet/akka.net/pull/5857)
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.
__Akka.Cluster.Tools__
[Add typed `ClusterSingleton` support](https://github.com/akkadotnet/akka.net/pull/6050)
[Singleton can use `Member.AppVersion` metadata to decide its host node during hand-over](https://github.com/akkadotnet/akka.net/pull/6065)
`Akka.Cluster.Singleton` can use `Member.AppVersion` metadata when it is relocating the singleton instance. When turned on, new singleton instance will be created on the oldest node in the cluster with the highest `AppVersion` number. You can opt-in to this behavior by setting `akka.cluster.singleton.consider-app-version` to true.
__Akka.Persistence.Query__
[Add `TimeBasedUuid` offset property](https://github.com/akkadotnet/akka.net/pull/5995)
__Akka.Remote__
[Fix typo in HOCON SSL settings. Backward compatible with the old setting names](https://github.com/akkadotnet/akka.net/pull/5895)
[Treat all exceptions thrown inside `EndpointReader` message dispatch as transient, Ported from 1.4](https://github.com/akkadotnet/akka.net/pull/5972)
[Fix SSL enable HOCON setting](https://github.com/akkadotnet/akka.net/pull/6038)
__Akka.Streams__
[Allow GroupBy sub-flow to re-create closed sub-streams, backported to 1.4](https://github.com/akkadotnet/akka.net/pull/5874)
[Fix ActorRef source not completing properly, backported to 1.4](https://github.com/akkadotnet/akka.net/pull/5875)
[Rewrite `ActorRefSink` as a `GraphStage`](https://github.com/akkadotnet/akka.net/pull/5920)
[Add stream cancellation cause upstream propagation, ported from 1.4](https://github.com/akkadotnet/akka.net/pull/5949)
[Fix `VirtualProcessor` subscription bug, ported from 1.4](https://github.com/akkadotnet/akka.net/pull/5950)
[Refactor `Sink.Ignore` signature from `Task` to `Task<Done>`](https://github.com/akkadotnet/akka.net/pull/5973)
[Add `SourceWithContext.FromTuples()` operator`](https://github.com/akkadotnet/akka.net/pull/5987)
