Very cool that even at this scale the right vanilla SQL database just works. No fancy document store, map-reduce, or GPU implementations needed.

How is ScyllaDB (the solution used in the article) a vanilla SQL DB? Its the complete opposite!

That... doesn't necessarily mean that it's a "vanilla SQL server"

It annoys me sometimes how effective B-trees are.

Every decade has some cool breakthrough in compression, and a handful of other disciplines. But OLTP databases are still basically better B-trees.

LSM trees? ScyllaDB is LSM-based storage engine. RocksDB as well.

Aren’t they using a NoSQL store? They migrated from Casandra to Scylla DB
