How to use UUIDs in Neo4j, to keep pointers to nodes elsewhere?

QUESTION

How to use UUIDs in Neo4j, to keep pointers to nodes elsewhere?

Asked 2020-Jan-16 at 12:35

I figured out thanks to some other questions that Neo4j makes use of ids for its nodes that could get recycled in case of node deletion.

That's a real concern for me as I need to store a reference to my node in another database (relational this time) in order to keep some sort of "pinned" nodes.

I've tried using this https://github.com/graphaware/neo4j-uuid to generate them automatically, but I did not succeed, all my queries kept running indefinitely.

My new idea is to make a new field in each of my nodes that I would manually fill with a UUID generated by NodeJs package uuid through uuid.v4().

I also came across the concept of indexing multiple times, which is totally unclear to me, but it seems that I should run this query: CREATE INDEX ON :MyNodeLabel(myUUIDField)

If you think that it doesn't make sense at all don't hesitate to come up with another proposition. I am open to all kinds of suggestions.

Thanks for your help.

I would consider using the APOC library's apoc.uuid.install procedure.

Definitely create a unique constraint on the label and attribute you are going to use. This will not only create an index but also guarantee uniqueness of the attribute in the label namespace.

Install neo4j-uuid

neo4j-uuid uses Gradle as build system. To install uuid-neo4j in a Neo4j server instance:.
call ./gradlew assemble
copy ./build/libs/neo4j-uuid.jar to your Neo4j server's plugins directory
copy the latest version of http://mvnrepository.com/artifact/com.fasterxml.uuid/java-uuid-generator to Neo4j's plugins directory as well (will automate that step in future).
amend $NEO4J_SERVER/conf/neo4j-server.properties with the following line: org.neo4j.server.thirdparty_jaxrs_classes=org.neo4j.extension.uuid=/db/uuid
