You can still call JMX operations from code, when you want, and hence cause state transfer to happen "on-demand” or lazily, without any manual intervention...

Thinking of using this as a lazy/on-demand form of state transfer in a distributed cluster, so joiners don’t trigger big chunks of data moving around eagerly.
