Neo4j: How to find all property names for a given node label

Question

In neo4j, is there a way to get the names of all properties for a given node label. There are plenty of articles explaining how to do this for a given node, but I need to get all property names for all nodes that belong to a give label.

Answer 1

You might want to use a sample of 1000 nodes if you have a big graph, as checking millions and millions of nodes might take time.

MATCH (n:Node)
WITH n LIMIT 1000
UNWIND keys(n) as key
RETURN distinct key

Answer 2

I'm no expert, but isn't this one way to do it?

MATCH(n:Movie)
UNWIND keys(n) AS movie_keys
RETURN DISTINCT movie_keys

Answer 3

call db.schema.nodeTypeProperties()
