Window functions are in draft, we will release them imminently. We will support moving averages. In fact we plan to support generic multi-pass and window functions. Having multi-pass will allow you to do things like `select sum(x -sum(x)) from tab`.

those things are so useless if your time points arent equidistant (ie, you don't care about the last 100 rows, you care about the last 5 minutes). they basically force you to use very slow correlated subqueries. please do something better.
