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.
Memgraph currently offers four data streams at Awesome Streams. These are the same streams that can be found at https://github.com/memgraph/data-streams. Spotify data stream is mentioned at https://github.com/memgraph/spotify-song-recommender.
You can open up the issue at https://github.com/memgraph/data-streams and ask for a Spotify stream to be included.
