Subject [Lucene-java Wiki] Trivial Update of "AvailableLockFactories" by SanneGrinovero
Date Sun, 29 Nov 2009 13:23:09 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Lucene-java Wiki" for change notification.

The "AvailableLockFactories" page has been changed by SanneGrinovero.


New page:
When applying changes to an index the Index``Writer needs to acquire an exclusive lock on
the Directory.

While both F``S``Directory and R``A``M``Directory have sensible defaults you might want to
consider an alternative for finetuning of performance, or because you are storing the index
on some multiple-node shared resource having issues with file based locking.
