I spent a bunch of time reading the website and I can't tell what this product does: Is it a database engine or an abstraction on top of other products?
If it's a database engine, then here are my thoughts: How is this database engine built to replace SQL and No-SQL? If it doesn't support JOINS why would I replace my SQL with it? Are transactions ACID? Why would anyone use this if there are no built-in user / group security mechanisms to protect data?
Seems like it's an layer over ElasticSearch using Presto SQL parser. SQL queries are translated into ES queries.
arthur, that's how we started two years ago. meanwhile the queries are being handled by our own engine. https://github.com/crate/crate
