What changed?

Requires ActiveClusterName to be set for active-active domains

Why?

Active-Active domains will use the ActiveClusterName as the "default" ActiveCluster for any workflows that do not specify a valid scope:name ClusterAttribute. This makes migration simple (existing domains can just start adding ClusterAttributes to divide work).

How did you test it?

Unit tests + simulations.
Canary to come.

Potential risks

The existing Canary or Simulation tests may start to fail. I plan on validating that they do not prior to merging.

Release notes

Active-Active domains now require an ActiveClusterName.
