I've been working on Skytable since 2020 and after several iterations from a simple K/V store, we've walked the path to this release. The goal of Skytable is to deliver a solid foundation for building apps; several implementations in Skytable (especially around query evaluation and execution) are fundamentally different from SQL and even NoSQL counterparts and there are some entirely new concepts which might make it a little hard to grasp.
Skytable's primary goal is performance and scale, and even with a query language it can outperform K/V stores which use simple commands (benchmarks will be posted soon).
BlueQL is a very important part of Skytable and it employs some interesting concepts to try and reduce the surface for injection attacks and tries to be a modern and secure alternative to SQL.
I'm here for any questions!
