repartition_graph(graph_name=None, options=)[source]

Rebalances an existing partitioned graph.

IMPORTANT: It’s highly recommended that you review the Graphs and Solvers concepts documentation, the Graph REST Tutorial, and/or some graph examples before using this endpoint.

Parameters

graph_name (str) –

Name of the graph resource to rebalance.

options (dict of str to str) –

Optional parameters. Allowed keys are:

  • new_graph_name – If a non-empty value is specified, the original graph will be kept (non-default behavior) 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 balanced 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 ‘’.

The default value is an empty dict ( ).

Returns

A dict with the following entries–

result (bool) –

Indicates a successful rebalancing on all servers.

info (dict of str to str) –

Additional information.
