Michael McCandless updated LUCENE-3203: --------------------------------------- Attachment: LUCENE-3203.patch New patch, applies to the IOContext branch. I think it's committable! It adds set/getMaxMergeWriteMBPerSec methods to FSDirectory. > Rate-limit IO used by merging > ----------------------------- > > Key: LUCENE-3203 > URL: https://issues.apache.org/jira/browse/LUCENE-3203 > Project: Lucene - Java > Issue Type: Improvement > Components: core/store > Reporter: Michael McCandless > Assignee: Michael McCandless > Priority: Minor > Fix For: 3.3, 4.0 > > Attachments: LUCENE-3203.patch, LUCENE-3203.patch > > > Large merges can mess up searches and increase NRT reopen time (see > http://blog.mikemccandless.com/2011/06/lucenes-near-real-time-search-is-fast.html). > A simple rate limiter improves the spikey NRT reopen times during big > merges, so I think we should somehow make this possible. Likely this > would reduce impact on searches as well. > Typically apps that do indexing and searching on same box are in no > rush to see the merges complete so this is a good tradeoff. -- This message is automatically generated by JIRA.
