Encounter warning when add edge in OrientDB

Here is my Code:

 OrientVertex luca = graph.addVertex(null);
 luca.setProperty("name", "John" + Integer.toString(i));

 OrientVertex marko = graph.addVertex(null);
 marko.setProperty("name", "Van Ness Ave." + Integer.toString(i + 1));

 OrientEdge lucaKnowsMarko = graph.addEdge(null, luca, marko, "knows");
 graph.commit();

Here is a snapshot of the same.

And then, I encountered this warning:

WARNING: The command 'create edge type 'knows' as subclass of 'E'' must be executed outside an active transaction: the transaction will be committed and reopen right after it. To avoid this behavior execute it outside a transaction (db=test)

Googling this problem, it seems that this question is relevant to the not-transactional and transactional databases operations.

You are working schema less, so OrientDB creates classes for you the first time you create vertexes/edges. In this case it was for the Edge class 'knows'. You can avoid this by creating classes at the beginning, or however, outside the scope of transaction. Try to execute this before your code, only once:

OrientGraphNoTx graph = new OrientGraphNoTx(url);
graph.createEdgeType("knows");
graph.shutdown();
