Subject [jira] Commented: (LUCENE-2655) Get deletes working in the realtime branch
Date Fri, 01 Oct 2010 17:58:34 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12916979#action_12916979

Jason Rutherglen commented on LUCENE-2655:
------------------------------------------

{quote}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.{quote}

Ok, that's the change you're referring to. In the current RT revision, the deletes are held
in one map in DW, guess we need to change that. However if we do, why do we need to keep the
seq id or docid as the value in the map? When the delete arrives into the DWPT, we know that
any buffered docs with that term/query need to be deleted on flush? (ie, lets *not* worry
about the RT search use case, yet). ie2, we can simply add the terms/queries to a set, and
apply them on flush, ala LUCENE-2679?

bq. NRT improvements

We're referring to LUCENE-1516 as NRT and LUCENE-2312 as 'RT'. I'm guessing you mean RT?
