Lucene Indexing Performance: Managing RAM while Indexing
https://issues.apache.org/jira/browse/LUCENE-843
This patch, by Michael McCandless pretty much sums up what I love about Lucene and what makes Lucene an extraordinary open source project.
Take Lucene, which already has a pretty strong reputation as being fast, and add in a motivated committer (which Lucene has a high number of, IMO) and out comes a patch that, at first blush, looks to blow the doors off even the old version of Lucene. And for those of you studying how Open Source “works”, take a look at the collaboration on the developer’s list related to this topic and a few ancillary topics. It really shows what goodness can come out of these types of communities.
Enjoy!
