@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.

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.
