I'm working on a platform where data changes in real-time, often every few milliseconds. It's not stored in a DB, and a lot of it is computed on-the-fly. What I want to query is a perfect fit for SQL. However, it's very much not in a database. I also don't need a subset of SQL. I would need things like stored procedures and ideally things like virtual tables. There's a lot of computation going on in the queries. The postgres can represent 100% of what I want, but it's a big complex syntax. In an ideal case, I could pick up pieces and run with them. I think I could reuse parts of things like a query optimizer too.
