[GitHub] [lucene] LuXugang commented on pull request #649: LUCENE-10408 Better encoding of doc Ids in vectors

LuXugang commented on PR #649:
URL: https://github.com/apache/lucene/pull/649#issuecomment-1088480302

   > I wonder if it would be a better trade-off to keep ints uncompressed, but read them from disk directly instead of loading giant arrays in memory? Or possibly switch to something like DirectMonotonicReader if it doesn't slow down searches.
   
   @jpountz, could we use IndexedDISI to store docIds and  DirectMonotonicWriter to store `ordToDoc` mapping like doc values did.
