20.14. Node degree

The node degree is the number of relationships associated with a node. Neo4j stores the degree for each node, making this a useful mechanism to quickly get the number of relationships a node has. You can also optionally filter degree by direction and/or relationship type.

Get the degree of a node

Return the total number of relationships associated with a node.

Get the degree of a node by direction and types

If you are only interested in the degree of a particular relationship type, or a set of relationship types, you specify relationship types after the direction. You can combine multiple relationship types by using the & character.
