如何禁用OrientDB中的自动类创建？

Question

How do I disable automatic class creation in OrientDB? I mean, suppose I create an edge like this:

sourceVertex.addEdge("PointsTo", targetVertex);

OrientDB will create a class PointsTo if it not already exists. Is it possible to configure OrientDB to throw an exception when a non-existent class is given?

Answer 1

Execute this SQL command against OrientDB database:

alter database custom useClassForEdgeLabel=false
