Subject [jira] Commented: (LUCENE-1313) Realtime Search
Date Mon, 01 Jun 2009 04:26:07 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714966#action_12714966

Jason Rutherglen commented on LUCENE-1313:
------------------------------------------

{quote}You can just temporarily set the default then run all
tests? {quote}

Or have separate parallel classes inherited classes that set the
static IW variable, run the tests, and perhaps have additional
NRT specific test methods.

{quote}I guess we could think about having it share/clone
internally?{quote}

Yeah we should, I got this confused with how we're cloning in
most o.a.l.i classes, but if we're calling openInput it seems
like we should have it internally clone, I guess we'll have an
issue with classes that don't IndexInput.close, however it's
better to solve these than open many unnecessary file
descriptors. 

{quote}let's take this up under a new issue?{quote}

The issue would only be the unit test for now, or should it be a
part of an existing issue? Ok, it will clean up LUCENE-1313's
unit test class.

> Enable near realtime search in Lucene without external
> dependencies. When RAM NRT is enabled, the implementation adds a
> RAMDirectory to IndexWriter. Flushes go to the ramdir unless
> there is no available space. Merges are completed in the ram
> dir until there is no more available ram. 
> IW.optimize and IW.commit flush the ramdir to the primary
> directory, all other operations try to keep segments in ram
> until there is no more space.
