How to load CSV data from a local directory into Memgraph and then run the DFS algorithm using Python?

CodePudding user response：

You should probably use the LOAD CSV Cypher clause in order to load the dataset. Here is a link to a simple guide that demonstrates how to load a CSV file step-by-step: https://memgraph.com/docs/memgraph/import-data/load-csv-clause

DFS: Did you try relationship traversals without specifying BFS as the method? This should result in a DFS traversal of the nodes and relationships. You can also specify the depth using the parameters minHopsand maxHops:

MATCH ({name: 'United Kingdom'})<-[:LIVING_IN*1..2]-(n)
RETURN n;
