Gremlin with Neptune：如何处理 Vertex ID 更新？

Question

Case:

A Customer Vertex ~Id requires an update in certain cases.

In the following case, what is the recommended approach to update a Vertex ~id with the New Vertex Id ?

Is this possible using an UPSERT or am I better to DELETE the old Vertex and then CREATE a new one assigning the New Vertex Id as ~id?

We have 20 million Vertex and approximately 2% of those will fall into this use case.

Customer Vertex updates

~id	New Vertex Id	Old Vertex Id
AAA	CCC	AAA
BBB	DDD	BBB

Answer 1

Vertex IDs in Neptune are immutable. If this is something that you need to change on a regular basis, then you'll want to make it a property instead.

Answer 2

@Sascha You can not change the vertex id once created as Taylor Riggan already mentioned. So your option would be to identify those rows and delete them and create new vertexes with new ids.
If you don't want to delete the old vertexes till new vertexes are created then you set say new attribute named "tobedeleted" to Y for the all identified old vertexes and then you create the new set vertexes and then delete the vertexes where "tobedeleted" property is set to Y.
