Hoss Man commented on LUCENE-475: --------------------------------- I'm no expert on File I/O, so i don't know if this is/isn't a good change to make, but i deplore constants: If this patch is a good idea, then i'd like to suggest that instead of a static constant for the buffer size, a new constructor arg be added specifying the buffer size, with the default (ie: no value, or "0" specified) being to use the old behavior (ie: a buffer the same size as the file) > 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.

For larger indexes this can be an issue. > I've attached patch how to solve this problem. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
