👋 do y'all have a high-level of idea of the amount of work to improve window function performance, I am seeing some high memory usage when increasing the number of window functions in a given transformation that have forced me back to Spark at this point for this specific transformation which has significantly lower memory usage and runtime, related to https://github.com/Eventual-Inc/Daft/issues/5316

Hey @Garrett Weaver, great question. I know @Euan Lim is planning on prioritizing window functions here soon after he finishes up some AsOf join work.
In addition to issue 5316, is there anything else you'd like to see from window functions?

Beyond the issue above, they have worked great. I'll open issues if anything else comes to mind.
