Neo4j has query that does K-Nearest-Neighbors  
BlogPost link:  
[https://neo4j.com/graphgist/movie-recommendations-with-k-nearest-neighbors-and-cosine-similarity#\_view\_your\_nearest\_neighbors](https://neo4j.com/graphgist/movie-recommendations-with-k-nearest-neighbors-and-cosine-similarity#_view_your_nearest_neighbors)

@pawanrawal has read the blogpost and figure the missing part from DGraph is the ability to do a cross product between two vectors.

It would be nice to have documentations or blogpost after this new feature is developed.

Hello! Is this a feature that has been already developed? Thanks

Nopes, we don’t have this feature yet.

You could load your graph from Dgraph into Spark (using spark-dgraph-connector) and then run an existing k-NN implementation for Spark.
