FAQ - Can I quiesce an individual namespace?
Each namespace has a separate set of partitions, and the
quiesce: command operates on the succession list of partitions, so shouldn’t it be possible to quiesce one namespace independently of the others on the node? This would avoid unnecessary migrations for namespaces that don’t need it during rolling restarts, for example.
This is actually not supported. Quiescing happens for all namespaces on a node at once.
To prioritize migrations of some namespaces before others, dynamically set the
migrate-order configuration variable.
