looks good, definitely the change to task execution is good, i'm a bit confused where we actually cancel requests now?

actually, do we want to do this? different layouts should handle projection with empty Mask efficiently on their own I would hope? plus now we defer creating the projection_evaluation which kills some of the pre-fetching right?

I don't think they actually do? For example, in flat layout we do:
let mut array = array.clone().await?;
let mask = mask.await?;

I think this directionally makes sense, just want to make sure we wire in cancelation. This will probably fix a lot of issues we've had reported about Vortex doing a surprising amount of IO against S3. |
