DELETE EDGE serve "player100" -> "team200"@0;
Is it possible to delete ALL “player100” → “team200” edges (rank:0, rank:1, …)?
Second question: This docs:
https://docs.nebula-graph.io/2.0/3.ngql-guide/13.edge-statements/1.insert-edge/ // Only the last write can be read
Does nebula graph store the multiple-inserted EDGE multiple times (and only the last can be read) or does the insert-statement overwrite an existing EDGE?
