Feasibility of supporting non-numeric vertex ID
Calvin Lei <ckp...@...>
I read this document - http://docs.janusgraph.org/latest/data-model.html and I wonder whether JanusGraph can support non-numeric vertex ID? Below is the pros/cons I came up. Did I overlook anything? Please chime in.
1. For storage backend that uses UUID, adding this feature will eliminate extra index lookup for JanusGraph's numeric ID
1. Not able to leverage JanusGraph's internal ID scheme (bit-wise)
2. Unpredictable column length for edges
3. Max degree of a vertex could reduce due to potential bigger columns
