Enable automatic UUIDs

This procedure is part of a set of procedures that handle automatic adding of UUID properties, via the UUID Handler Lifecycle. The UUID handler is a transaction event handler that automatically adds the UUID property to a provided label and for the provided property name.

By default automatic adding of UUIDs is disabled. We can enable it by setting the following property in apoc.conf:

apoc.conf
apoc.uuid.enabled=true

Usage Examples

We can remove a UUID handler (installed by apoc.uuid.install), by running the following query:

CALL apoc.uuid.remove("Person");
Table 1. Results
label installed properties

"Person"

FALSE

{uuidProperty: "myUUID"}

If we try to remove a non existent UUID handler, the output will indicate that no such handler is installed:

CALL apoc.uuid.remove("Foo");
Table 2. Results
label installed properties

NULL

FALSE

{}
