[jira] Commented: (LUCENE-1313) Near Realtime Search
[ https://issues.apache.org/jira/browse/LUCENE-1313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12719767#action_12719767 ]
Jason Rutherglen commented on LUCENE-1313:
------------------------------------------
TestThreadedOptimize is throwing a ensureContiguousMerge
exception. I think this is highlighting the change to merging
all ram segments to a single primaryDir segment can sometimes
lead to choosing segments that are non-contiguous? I'm not sure
of the best way to handle this.

> 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.
