Method Detail

create

public BulkLoaderVertexProgram create(Graph graph)

Specified by:

create in interface VertexProgram.Builder

Overrides:

create in class AbstractVertexProgramBuilder<BulkLoaderVertexProgram.Builder>

bulkLoader

public BulkLoaderVertexProgram.Builder bulkLoader(String className)

Sets the class name of the BulkLoader implementation to be used.

bulkLoader

public BulkLoaderVertexProgram.Builder bulkLoader(Class<? extends BulkLoader> clazz)

Sets the class of the BulkLoader implementation to be used.

vertexIdProperty

public BulkLoaderVertexProgram.Builder vertexIdProperty(String name)

Sets the name of the property that is used to store the original vertex identifiers in the target graph.

userSuppliedIds

public BulkLoaderVertexProgram.Builder userSuppliedIds(boolean useUserSuppliedIds)

Specifies whether user supplied identifiers should be used when the bulk loader creates vertices in the target graph.

keepOriginalIds

public BulkLoaderVertexProgram.Builder keepOriginalIds(boolean keepOriginalIds)

Specifies whether the original vertex identifiers should be kept in the target graph or not. In case of false BulkLoaderVertexProgram will add another iteration to remove the properties and it won't be possible to use the data for further incremental bulk loads.

intermediateBatchSize

public BulkLoaderVertexProgram.Builder intermediateBatchSize(int batchSize)

The batch size for a single transaction (number of vertices in the vertex loading stage; number of edges in the edge loading stage).

writeGraph

public BulkLoaderVertexProgram.Builder writeGraph(String configurationFile)
                                           throws ConfigurationException

A configuration for the target graph that can be passed to GraphFactory.open().

Throws:

ConfigurationException

writeGraph

public BulkLoaderVertexProgram.Builder writeGraph(Configuration configuration)

A configuration for the target graph that can be passed to GraphFactory.open().
