Subject [jira] Commented: (LUCENE-2471) Supporting bulk copies in Directory
Date Mon, 24 May 2010 10:34:23 GMT


Michael McCandless commented on LUCENE-2471:

I think this issue makes sense, separate from LUCENE-2455?  Ie this issue is for bulk copying
when you have IndexInput/Output already open (I don't think LUCENE-2455 covers this?).  Whereas
LUCENE-2455 is operating on file names...

> A method can be added to IndexOutput that accepts IndexInput, and writes bytes using
it as a source.
> This should be used for bulk-merge cases (offhand - norms, docstores?). Some Directories
can then override default impl and skip intermediate buffers (NIO, MMap, RAM?).
