Multiple properties of node to identify node Uniquely

Question

Can we have multiple properties of a node to identify it uniquely in neo4j graph database?

Something like composite primary key, in RDBMS, to uniquely identify a row of a table.

Unfortunately not. The best that you can do at the moment is to create a property which concatenates the properties that you want to uniquely identify and put a constraint on that.

You can use an array property and create index on that.

As of now, neo4j(v3.0.3) still does not support unique constraint with multiple properties. The reason behind this is: When a unique constraint is created it also creates an index on it and as indexes only allow one property, thus constraints can only be applied on one index.
