1.4.14 December 30 2020
Maintenance Release for Akka.NET 1.4
Akka.NET v1.4.14 contains some significant bug fixes and improvements. It is a highly recommended upgrade for all Akka.NET users.
Major Reduction in Idle CPU Usage and Latency for Akka.Remote
One of the most important fixes introduced in Akka.NET v1.4.14 is the new self-tuning batching system for Akka.Remote's DotNetty transport, which simulatneously reduces idle CPU consumption on low-traffic systems by as much as 55% while improving latency by a factor of 10 for low-traffic systems.
The batching system no longer needs to be configured - it can scale up and down with workload automatically in order to both maximize throughput with a minimal amount of latency. You can read more about it here: https://getakka.net/articles/remoting/performance.html
Other bug fixes and improvements:
- Akka: Move RouterActor routing logic controller actor instantiation from OnReceive to constructor
- Akka.Streams: Serializing a
SinkRefwrapped inside a POCO failed - Akka.Persistence: Akka.NET Should Allow Separate Read and Write Event Adapter Bindings
- Akka.Persistence.Query: Added Timestamp to
EventEnvelope- breaking API change; will require all Akka.Persistence plugins to be recompiled and updated. - Akka.Remote: fix NRE inside
RemotingTerminator
