Wonder why they didn't use Cassandra for this use case.

Yes. Aphyr has an excellent article on Cassandra.https://aphyr.com/posts/294-call-me-maybe-cassandra/

What makes you recommend Cassandra here over the other?

Does this article imply that don't use Cassandra. Use ScyllaDB when you think you want Cassandra

Cassandra's out. It's whole design is for work loads with lots of writes mixed in.

Maybe your startup just sucked at Cassandra?

How about BigTable and Cassandra?

sharadov Apr 14, 2017 View on HN

Really Cassandra? No way does it compare to mature RDBMS's like Postgres, MySQL or SQL server.

Cassandra is ugly, hardcore and performant as hell. It's not meant for the casual user, it's really meant to be there for you at scales where MongoDB craps its pants. If you wrap your head around ColumnFamilies, tunable consistency and NetworkTopologySnitch strategies, you get rewarded by a database that can scale on a global level to millions of I/O operations per second. We at Trademob have chosen Cassy as the backbone of our tracking platform and couldn't be happier. It's pretty serious stuff
