35.2. Batch Graph Database

Prev		Next

In case you already have code for data import written against the normal Neo4j API, you could consider using a batch inserter exposing that API.

	Note
	This will not perform as good as using the `BatchInserter` API directly.

Also be aware of the following:

Starting a transaction or invoking Transaction.finish()/close() or Transaction.success() will do nothing.
Invoking the Transaction.failure() method will generate a NotInTransaction exception.
Node.delete() and Node.traverse() are not supported.
Relationship.delete() is not supported.
Event handlers and indexes are not supported.
GraphDatabaseService.getRelationshipTypes(), getAllNodes() and getAllRelationships() are not supported.

With these precautions in mind, this is how to do it:

GraphDatabaseService batchDb =
        BatchInserters.batchDatabase( "target/batchdb-example", fileSystem );
Label personLabel = DynamicLabel.label( "Person" );
Node mattiasNode = batchDb.createNode( personLabel );
mattiasNode.setProperty( "name", "Mattias" );
Node chrisNode = batchDb.createNode();
chrisNode.setProperty( "name", "Chris" );
chrisNode.addLabel( personLabel );
RelationshipType knows = DynamicRelationshipType.withName( "KNOWS" );
mattiasNode.createRelationshipTo( chrisNode, knows );
batchDb.shutdown();
