Method Detail

vertexIdKey

public BatchGraph.Builder vertexIdKey(java.lang.String key)

Sets the key to be used when setting the vertex id as a property on the respective vertex. If this value is not set it defaults to T.id.

Parameters:

key - Key to be used.

edgeIdKey

public BatchGraph.Builder edgeIdKey(java.lang.String key)

Sets the key to be used when setting the edge id as a property on the respective edge. If the key is null, then no property will be set.

Parameters:

key - Key to be used.

bufferSize

public BatchGraph.Builder bufferSize(long bufferSize)

Number of mutations to perform between calls to Transaction.commit().

vertexIdType

public BatchGraph.Builder vertexIdType(VertexIdType type)

Sets the type of the id used for the vertex which in turn determines the cache type that is used.

incrementalLoading

public BatchGraph.Builder incrementalLoading(boolean incrementalLoading)

Sets whether the graph loaded through this instance of BatchGraph is loaded from scratch (i.e. the wrapped graph is initially empty) or whether graph is loaded incrementally into an existing graph.

In the former case, BatchGraph does not need to check for the existence of vertices with the wrapped graph but only needs to consult its own cache which can be significantly faster. In the latter case, the cache is checked first but an additional check against the wrapped graph may be necessary if the vertex does not exist.

By default, BatchGraph assumes that the data is loaded from scratch.

incrementalLoading

public BatchGraph.Builder incrementalLoading(boolean incrementalLoading,
                                             java.util.function.BiConsumer<Element,java.lang.Object[]> existingVertexStrategy,
                                             java.util.function.BiConsumer<Element,java.lang.Object[]> existingEdgeStrategy)

Sets whether the graph loaded through this instance of BatchGraph is loaded from scratch (i.e. the wrapped graph is initially empty) or whether graph is loaded incrementally into an existing graph.

In the former case, BatchGraph does not need to check for the existence of vertices with the wrapped graph but only needs to consult its own cache which can be significantly faster. In the latter case, the cache is checked first but an additional check against the wrapped graph may be necessary if the vertex does not exist.

By default, BatchGraph assumes that the data is loaded from scratch.
