Class OneTimeBulkLoader

java.lang.Object

org.apache.tinkerpop.gremlin.process.computer.bulkloading.OneTimeBulkLoader

All Implemented Interfaces:

BulkLoader

Deprecated.

As of release 3.2.10, not directly replaced - consider graph provider specific bulk loading methods

@Deprecated
public class OneTimeBulkLoader
extends Object
implements BulkLoader

OneTimeBulkLoader is a BulkLoader implementation that should be used for initial bulk loads. In contrast to IncrementalBulkLoader it doesn't store temporary identifiers in the write graph nor does it attempt to find existing elements, instead it only clones each element from the source graph.
