Michael McCandless commented on LUCENE-2795: -------------------------------------------- Also, we should run some more tests here, on modern kernels, since the SEQUENTIAL fadvise flag is better implemented in kernels >= 2.6.29; see this comment: http://blog.mikemccandless.com/2010/06/lucene-and-fadvisemadvise.html?showComment=1303235497682#c2572106601600642254 It could be, if kernel is new enough, we should not do DIRECT and instead do SEQUENTIAL. > Genericize DirectIOLinuxDir -> UnixDir > -------------------------------------- > > Key: LUCENE-2795 > URL: https://issues.apache.org/jira/browse/LUCENE-2795 > Project: Lucene - Java > Issue Type: Improvement > Components: core/store > Reporter: Michael McCandless > Assignee: Varun Thacker > Labels: gsoc2011, lucene-gsoc-11, mentor > Attachments: LUCENE-2795.patch, LUCENE-2795.patch, LUCENE-2795.patch, > LUCENE-2795.patch, LUCENE-2795.patch > > > Today DirectIOLinuxDir is tricky/dangerous to use, because you only want to > use it for indexWriter and not IndexReader (searching). It's a trap. > But, once we do LUCENE-2793, we can make it fully general purpose because > then a single native Dir impl can be used. > I'd also like to make it generic to other Unices, if we can, so that it > becomes UnixDirectory. -- This message is automatically generated by JIRA.
