Subject [jira] Commented: (LUCENE-1539) Improve Benchmark
Date Thu, 23 Apr 2009 00:48:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1539?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12701768#action_12701768

Jason Rutherglen commented on LUCENE-1539:

I think it should mean "delete XXX% of the remaining
undeleted docs"?
{quote}

Yeah? Ok. So the deleteDocsByPercent method needs to somehow
take into account whether it's deleted before by adjusting the
doc nums it's deleting?

{quote}
I don't think we can relax that. This (single transaction
(writer) open at once) is a core assumption in Lucene.

True, however doesn't mean we have to stick with it, especially
internally. Hopefully we can move to a more componentized model
someone could change this if they wanted. Perhaps in the
flexible indexing revamp?
