Michael McCandless commented on LUCENE-10574:
---------------------------------------------
If any one finally gives a talk about "How Lucene developers try to use
algorithms that minimize adversarial use cases", this might be a good example
to add. We try to choose algorithms that minimize the adversarial cases even
if it means sometimes slower performance for normal usage. Maybe someone could
submit this talk for ApacheCon :)

> Remove {{floorSegmentBytes}} parameter, or change lucene's default to a merge
> policy that doesn't merge in an O(n^2) way.
> I have the feeling it might have to be the latter, as folks seem really wed
