Enclosing class:

RepartitionGraphRequest

public static final class RepartitionGraphRequest.Options
extends Object

Optional parameters.

• NEW_GRAPH_NAME: If a non-empty value is specified, the original graph will be kept (non-default behaviour) and a new balanced graph will be created under this given name. When the value is empty (default), the generated 'balanced' graph will replace the original 'unbalanced' graph under the same graph name. The default value is ''.
• SOURCE_NODE: The distributed shortest path solve is run from this source node to all the nodes in the graph to create balaced partitions using the iso-distance levels of the solution. The source node is selected by the rebalance algorithm automatically (default case when the value is an empty string). Otherwise, the user specified node is used as the source. The default value is ''.
• SQL_REQUEST_AVRO_JSON: The default value is ''.

The default value is an empty Map. A set of string constants for the parameter options.
