A custom partitoner specifically for RDDs made for DseGraph.
The general idea is
For a vertex
Determine the ~label property
Determine which RDD represents the data in that label
Determine the C* token of the vertex given it's label
Determine which partition in the found RDD would contain that Token
Determine the offset of that RDD's partitions in the UnionRDD
Return the partition index added to offset

For a given Map based Vertex Key determine which table it belongs to.
For a given Map based Vertex Key determine which table it belongs to. From this table lookup the correct
RDD and the partitioning for that RDD. Once narrowed down generate the Token given the now known table. This
token will then be compared against the quick lookup Bucket structure for that RDD. We then add that partition
index to the offset for that RDD.
