Once you’re happy with the results, you can persist them in the knowledge graph. You could simply use the write version of the algorithm (gds.wcc.write), which annotates each node with the connected component identifier, and then use that to create master entities.

Instead, the Cypher script in Example 9-14 uses the output of the stream version of the algorithm to create a customized persisted representation of the connected components. The subgraph created is itself a representation of the master entity (the golden record). The same script connects all matched records to the master entity, enabling traceability.
