  2. JanusGraphIndex how to retrieve constraint (indexOnly) specified for the global index?

Re: JanusGraphIndex how to retrieve constraint (indexOnly) specified for the global index?

You can do this:
JanusGraphSchemaType constraint = ManagementSystem.getGraphIndexDirect("indexName", ((ManagementSystem) mgmt).getWrappedTx()).getSchemaTypeConstraint();
If (constraint == null) then there is no constraint. Otherwise constraint.name() returns your indexOnly label.

Best regards,
Boxuan

Thanks. Still, my earlier answer remains unsatisfactory. Somehow, a new JanusGraph instance must be able to load an existing schema from the system table and have the information about label constraints available. Otherwise, the instance would not be able to index newly added vertices and edges correctly.

Best wishes,   Marc
