Subject [jira] [Commented] (LUCENE-3416) Allow to pass an instance of RateLimiter to FSDirectory allowing to rate limit merge IO across several directories / instances
Date Tue, 06 Sep 2011 14:09:09 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3416?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13098018#comment-13098018

Shay Banon commented on LUCENE-3416:
------------------------------------

It is possible, but requires more work to do, and depends on overriding the createOutput method
(as well as all the other methods in Directory). If rate limiting makes sense on the directory
level to be exposed as a "feature", I think that this small change allows for greater control
over it.

> This can come in handy when running several Lucene indices in the same VM, and wishing
to rate limit merge across all of them.
