Computing a node’s degree with GDS

We have studied the node degree metric and its distribution in the preceding chapter, Chapter 3, Characterizing a Graph Dataset. At that time, we computed the node’s degree using a Cypher query. GDS provides a procedure to perform the same computation, on a projected graph. We are now going to use this procedure, whose results are well known, in order to understand the different algorithm modes and configuration options.

All algorithm procedures from GDS use the same syntax:

gds.<algoName>.<executionMode>(<graphName>, <algoConfiguration>)

Here, the following applies:

• algoName is the name of the algorithm. Note that some algorithms are included in an alpha or beta version, in which case they are accessible via gds.alpha.<algoName> or gds.beta.<algoName>.
• executionMode is one of stream, write, mutate, estimate or stats, as defined in the GDS project workflow section.
• graphName...
