Michael McCandless commented on LUCENE-9388:
--------------------------------------------
Memory mapped IO is likely plenty fast, but there may indeed be some overhead
versus the {{long[]}} that backs our typical live docs implementations?
Since live docs are mostly accessed forward only iterator style (like doc
values), maybe switching the random access {{BitSet}} we use today to an
iterator over bits is the first step? We might also want to invert it
(again!!), so the iterator's {{.next()}} advances to the next deleted doc,
since for most indices more documents are live than not.
We should just try it and see :)
