Unique Value of UUID across Labels

Neo4j Graph Platform Procedures & APOC
1

Hi,

I want to make sure the uuid value is unique across my labels in the database.

Using the following procedure I can make uuid unique in a particular label

CREATE CONSTRAINT FOR (t:Person) REQUIRE t.uuid IS UNIQUE
CALL apoc.uuid.install("Person", {addToExistingNodes : false});

But how to make it unique across the whole db?

Any help is much appreciated.

Thanks,
Sahil

A uuid is universally unique by design.

So apoc.create.uuid() always returns an unique uuid value for my database?

Yes, If it is a proper implantation.

The preferred function for generating a uuid is "randomUUID()". I believe the apoc function has been deprecated.
