Subject [jira] Commented: (LUCENE-1313) Realtime Search
Date Mon, 15 Jun 2009 17:46:07 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12719665#action_12719665

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

Just wanted to give an update on this, I'm running the unit
tests with flushToRAM=true, the ones that fail are (mostly)
tests that look for files when they're now in RAM (temporarily)
and the like. I'm not sure what to do with these tests, 1)
ignore them (kind of hard to not run specific methods, I think)
2) or conditionalize them to run only if flushToRAM=false.

> 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.
