Thanks for the demo. In the beginning of the video your diagram showed key-value stores being replicated to the leaf nodes, but you did not cover this in your presentation. It seems replicating KVs is not as straight forward as regular streams - is it even possible? We were hoping to use leaf-nodes and KVs and have leaf-nodes update values in KVs that would then be updated in the cluster. Hoping you can shed some light on this.
I want to understand JetStream domains better. Let's say that I have images generated by a disconnected leaf (like a car). When the leaf regains connectivity, I'd like the images to be copied to the cluster in the cloud, which is used by a global website. However, I also have local apps in the car that will want fast access. How would this setup be configured?
Looks great. Would be nice to show example with strict security when leafnode cannot query all subjects with global js-domain. Only specific. Or maybe it is show in some other videos.
Trying to connect a leaf node between 2 cluster. Both in operator mode. Cluster A is source, cluster B is leaf. The remote nodes declaration require an account nkey in order to establish the leaf connection. The nkey is verified in cluster A, but unknown in cluster B. If a configure the cluster B's nkey, then verification failed in cluster A. WTF ?
great examples from practice. Thanks!
read replica only? can the leaf write?

Hey! It is possible to do but a bit cumbersome. We have some features coming in NATS server 2.10 that will make this much easier to do
@@SynadiaCommunications I'm interested in this too, is there a recent example with v2.10 features you mention?

Yup, lots more videos we can do on leafnode security
@@SynadiaCommunications looking forward to new videos!

Ok found it. Requiring the account key does not imply that I don't need to provide credentials ^^
bRrrrUp ... sync back up to the cloud. I like that.
Super powers
I like to think so
leaf nodes are automagically
It still blows my mind
