I’m pretty sure there is a bug there. I’m working on Boron-SR1. I am doing a read on ElanInterfaces with InstanceIdentifier: InstanceIdentifier.create(ElanInterfaces.class) On the result I’m invoking: ElanInterfaces.getElanInteface().size(). Result is 6. Next line of code I’m registering a ClusteredDataTreeChangeListener on ElanInterface: InstanceIdentifier.create(ElanInterfaces.class).child(ElanInterface.class)). The first onDataTreeChanged I’m getting contains only one DataTreeModification. In subsequent notifications I’m getting the rest of the pre-existing data. This same behavior repeats itself in other entities too, and in different setups.

If you're getting subsequent data then that must have occurred after your registration.

Will all the existing data be received in a single “onDataTreeChanged” invocation? I’m registering a ClusteredDataTreeChangeListener in my usecase, and I see that I don’t receive all the data in the first call.
