I have found four sets that can be ingested directly into Memgraph at Awesome Streams site. I've also found a tutorial How to build a Spotify Recommendation Engine using Kafka and Memgraph.
Is there a public stream of this dateset? I know that I can download it, and I know that there is an already app but I'd like for a public stream so that I can showcase this in my school without need for bringing my laptop.
