Node1 -[rel1]-> Node2
Node1 -[rel2]-> Node3
...... CSV file 1 ......
Node1 -[rel3]-> Node4
Node1 -[rel4]-> Node5
...... CSV file2 ......
for example, i need to delete the rel2, it is eaiser to do it actually, but when using LOAD CSV, seems I need to LOAD the same CSV file twice: 1) delete the relationships 2) re-create the relationship between the nodes, this will involve the not only the IO resource I think.
and for my case, those relationships in multile CSV file, so I cannot DETACH DELETE the nodes when looping the "CSV file 1", this will delete the rel2 and rel3 but this is not as expect.
