Greg Bowyer commented on LUCENE-3178: ------------------------------------- Tangentially I have been futzing a little with this based on some observations I noticed around madvise http://people.apache.org/~gbowyer/madvise-perf/index.html > Native MMapDir > -------------- > > Key: LUCENE-3178 > URL: https://issues.apache.org/jira/browse/LUCENE-3178 > Project: Lucene - Core > Issue Type: Improvement > Components: core/store > Reporter: Michael McCandless > Labels: gsoc2012, lucene-gsoc-12 > > Spinoff from LUCENE-2793. > Just like we will create native Dir impl (UnixDirectory) to pass the right OS > level IO flags depending on the IOContext, we could in theory do something > similar with MMapDir. > The problem is MMap is apparently quite hairy... and to pass the flags the > native code would need to invoke mmap (I think?), unlike UnixDir where the > code "only" has to open the file handle. -- This message is automatically generated by JIRA.
