Re: Inconsistent composite index status after transaction failure
The janusgraph docs and gitrepo talk about ghost vertices or phantom vertices:
What happens if you try to delete the vertex with my_id = 2?
If this works, I am afraid there is not a more helpful answer than:
If deleting the vertex does not work, you might want to mention this discussion in issue 2176, explaining why your issue is different from a ghost vertex.
Best wishes, Marc
