RelationshipStreamExporterBuilder

public RelationshipStreamExporterBuilder()

Method Details

build

public abstract RelationshipStreamExporter build()

withIdMappingOperator

public RelationshipStreamExporterBuilder withIdMappingOperator(LongUnaryOperator toOriginalNodeId)

withTerminationFlag

public RelationshipStreamExporterBuilder withTerminationFlag(org.neo4j.gds.termination.TerminationFlag terminationFlag)

withRelationships

public RelationshipStreamExporterBuilder withRelationships(Stream<org.neo4j.gds.api.ExportedRelationship> relationships)

withRelationshipCount

public RelationshipStreamExporterBuilder withRelationshipCount(long relationshipCount)

withBatchSize

@TestOnly
public RelationshipStreamExporterBuilder withBatchSize(int batchSize)

withProgressTracker

public RelationshipStreamExporterBuilder withProgressTracker(org.neo4j.gds.core.utils.progress.tasks.ProgressTracker progressTracker)

Set the ProgressTracker to use for logging progress during export. If a TaskProgressTracker is used, caller must manage beginning and finishing the subtasks. By default, an ProgressTracker.EmptyProgressTracker is used. That one doesn't require caller to manage any tasks.

Parameters:

progressTracker - The progress tracker to use for logging progress during export.

Returns:

this

withArrowConnectionInfo

public RelationshipStreamExporterBuilder withArrowConnectionInfo(Optional<org.neo4j.gds.config.ArrowConnectionInfo> arrowConnectionInfo,
 Optional<String> remoteDatabaseName)

withConcurrency

public RelationshipStreamExporterBuilder withConcurrency(int concurrency)

withResultStore

public RelationshipStreamExporterBuilder withResultStore(Optional<org.neo4j.gds.api.ResultStore> resultStore)
