ANNOUNCE: New Remoting Milestone 1
Patrik Nordwall
Dear hakkers,
We’re excited to announce that we have released the first development milestone of the new Akka Remoting, which has the code named Artery. It’s an early development preview and we encourage you to try it out and give us feedback, but it’s not intended for production usage yet.
The version number is 2.4-ARTERY-M1 with same artifacts as usual.
It is enabled with the following configuration:
akka.remote.artery {
enabled = on
# The hostname or ip clients should connect to.
hostname = localhost
# use 0 if you want a random available port
port = 20200
}
The protocol part of the actor system address is artery (*), so you need to change previous akka.tcp to artery in for example configuration of cluster seed-nodes.
The key features of Artery compared to current implementation will be:
support high throughput and low latency, such as 1,000,000 msg/s and sub-millisecond latency (more details in the design document, and no hard promises yet)
improved cluster stability by using isolated streams for control messages, this means less false failure detection in case of heavy message traffic
reduce message envelope overhead by smart compression of actor references and other header information
make it possible to use efficient serialization with ByteBuffers directly
protocol stability between major Akka versions to support for example rolling upgrade deployments (the protocol is however incompatible with current TCP based protocol)
internal design that is easier to maintain
We are using Aeron as the underlying transport and are implementing the layers on top using Akka Streams. You find more details in the design document.
The development branch is artery-dev, in case you want to take a look or contribute. Issues are labeled with t:remoting:artery.
Cheers,
Patrik Nordwall
