Thanks for the background. I find it fascinating that the small-data scenarios in analytics are still kind of chaotic when it comes to tooling. Full-fledged SQL queries on relations seems heavy but closer to raw data. The timevector custom data type is like a middle ground. Each timevector is essentially a pre-aggregated time series (maybe compressed also) so approach likely adds performance benefit when the task is to analyze many many small time series. Although I still feel supporting 70+ new functions adds a lot of maintenance burden, and people cannot debug/extend this set of functions because they are not SQL. I am wondering if you often find that users just want an out-of-box solutions or they need to have the ability to tweak or adding their own domain-specific logic.
