Hi Kaspar,
In your first example, you're trying to permanently change the bucket's r
parameter; createBucket() returns a WriteBucket which when executed writes
these values to Riak. We currently don't have support for this in the protobuf
API.
In your DomainBucket example you're setting the r value for the individual read
operations (which is supported via PB), rather than bucket parameter itself. It
gets passed to the underlying StoreObject.
Thanks,
Brian Roach
