Took advantage of the lunch break to replay this great talk by Alfonso Subiotto (@asubiotto.com) making the case for a State Machines based approach to Deterministic Simulation Testing, being used at @polarsignals.com, very interesting!

Their inspiration for this: sled.rs/simulation

Thanks for the pointer. Do you know where though? This is what I could find of the representation: github.com/vortex-data/.... Also the pushed-down filter kernel seems to convert to arrow and delegate: github.com/vortex-data/.... In arrow I'm pretty sure the prefixes are not a separate array.

Haha, but thanks for pointing this out. Now I'm going to have to do a little researching

Unfortunately no plans to be in SF around then but we'll keep it in mind in case anyone does end up being there.
