Subject [jira] [Commented] (LUCENE-2558) Use sequence ids for deleted docs

Simon Willnauer commented on LUCENE-2558:
-----------------------------------------

bq. Does anybody know where to checkout the realtime branch? I am very interested in it! Thanks!
there is no realtime branch open right now. We had to delete it since we re-integrated it
for DocumentsWriterPerThread. (SVN requires that once you have re-integrated) However, there
is no development happening along those lines right now and we didn't decide if we move forward
since for general purpose the NRT features we have is reasonably fast. Anyway, I think there
is still a need for this if we can provide it as a non-default option?
