[ http://issues.apache.org/jira/browse/LUCENE-475?page=comments#action_12359098 ]
Doug Cutting commented on LUCENE-475: ------------------------------------- Why not just use BufferedIndexOutput.BUFFER_SIZE, a constant declared elsewhere and already used for all RAMDirectory buffers? That way you're not introducing any new constants and disturbing the constant averse... And I disagree that the default behaviour should be as before: there's no good reason to buffer the entire file. That was a bug that this patch fixes. > RAMDirectory(Directory dir, boolean closeDir) constructor uses memory > inefficiently. > -------------------------------------------------------------------------------------- > > Key: LUCENE-475 > URL: http://issues.apache.org/jira/browse/LUCENE-475 > Project: Lucene - Java > Type: Improvement > Components: Store > Reporter: Volodymyr Bychkoviak > Attachments: RamDirectory.diff > > recently I found that RAMDirectory(Directory dir, boolean closeDir) > constructor uses memory inefficiently. > files from source index are read entirely intro memory as single byte array > which is after all is thrown away.
