Michael McCandless commented on LUCENE-2655:
--------------------------------------------
bq. Are you saying we should simply make deletes work (as is, no BytesRefHash
conversion) then cleanup the RT branch as a merge to trunk of the DWPT changes?
Yes! Just keep using the Map we now use, but now it must be per-DWPT. And
when IW.deleteDocs(Term/Query) is called, we must go to each DWPT, grab its
current docID, and enroll Term/Query -> docID into that DWPT's pending deletes
map.
bq. Also, from what I've seen, deletes seem to work, I'm not sure what exactly
Michael is referring to.
But this is using the long sequenceID right? (adds 8 bytes per buffered
docID). I think we wanted to explore ways to reduce that? Or, if we can make
it modal (you only spend these 8 bytes if IW is open in NRT mode), then that's
OK?
I was hoping to cleanly separate the DWPT cutover (solves the nasty flush
bottleneck) from the NRT improvements.
