I think no user understands what they are supposed to do when they should define a "backing state backend".

The most common thing will probably be that the RocksDB snapshots are backed up to HDFS and that this is also the backing state backend.

A simple constructor with a single URI/Path/String that configures both at the same time should be added, to make this accessible to users.
