A fluid.datasetfilter~ object for conditional querying

In that patch around half the time is taken up by the dump , so I guess it hinges on whether you really need that.

Yes. They trade off mutability for some simplicity, making them relatively simple to implement and good enough for many purposes.

I wonder if there’s a way of reformulating what you want to do in terms of first querying a fixed all-in kdtree, and then filtering the results of that based on more flexible criteria? That would avoid re-fitting ( expensive, always will be), but also yields a smaller set to filter.

That’s exactly where seeing some abstractions developed to cope with the mess is helpful. E.g., I could imagine storing protoype query messages in a coll

One of Max’s greatest problems is that it tends towards mess very quickly, so any coping strategies are always interesting to see
