This is the first release since April, and it’s a massive release bringing many enhancements and new features.
We are introducing Choria Streams - a Stream Processing framework built into the Choria Broker powered by NATS JetStream. I wrote a blog post about this Introducing Choria Streams that’s worth a read.
Other major enhancements are that we now support Websockets for the network connections between Servers, Broker and Go clients.
Autonomous Agents now have a data layer meaning within an Autonomous Agent data can be fetched from stores like other Key-Value stores and this data can be accessed by Watchers at run time. We expose node facts to Autonomous Agents in the data layer. Additionally, we support watching Choria Key-Value Store for changes which updates the data layer and trigger transitions. Exec Watchers also support Governors to create orchestration-free rolling upgrades etc.
We made huge improvements to Provisioning, we blogged about this in Provisioning HA and Security. There you can also see we support Leader Election against Choria Streams as a library feature.
On the documentation front we added a big section about Choria Streams but also received permission to Open Source some documentation that shows how a very large - millions of nodes - Choria deployment might look. This is a proven design in active use in production for a few years already. We are busy building another such network at the moment, and a lot of the enhancements in Provisioning is as a result of this work. Find the document at Large Scale Design.
