-Re: Behavior of Filter.transform() in FilterList?

You want transform to only be called on filters that are "reached"?
I.e. FilterA and FilterB, FilterB.transform should not be called if a KV is already filtered by FilterA?
That's not how it works right now, transform is called in a completely different code path from the actual filtering logic.

Yes, that would be FilterList(OR, [FilterList(AND, [family=X, column=Y,
KeyOnlyFilter]), FilterList(AND, [family=A, column=B])]).
So the behavior is expected.
Could you explain, I'm not sure how you reach this conclusion.
Are you saying it is expected, given the actual implementation
Or are there some other details I missed?
