Simon Willnauer commented on LUCENE-8321:
-----------------------------------------

I like this idea a lot. It's progress over perfection and it would simplify the accounting in IW dramatically (on the other hand I think it's nice to have this accounting for assertion purposes ie. just to make sure we have correct counts)!!

> I would like to start discussing removing the limit of ~2B documents that we have for indices, while still enforcing it at the segment level for practical reasons.
> Postings, stored fields, and all other codec APIs would keep working on integers to represent doc ids. Only top-level doc ids and numbers of documents would need to move to a long. I say "only" because we now mostly consume indices per-segment, but there is still a number of places where we identify documents by their top-level doc ID like {{IndexReader#document}}, top-docs collectors, etc.
