             Summary: Create a move method in Directory.
                 Key: LUCENE-4746
                 URL: https://issues.apache.org/jira/browse/LUCENE-4746
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Mark Miller
            Assignee: Mark Miller
             Fix For: 4.2, 5.0


I'd like to make a move method for directory.

We already have a move for Solr in DirectoryFactory, but it seems it belongs at the directory
level really.

The default impl can do a copy and delete, but most implementations will be able to optimize
to a rename.

Besides the move we do for Solr (to move a replicated index into place), it would also be
useful for another feature I'd like to add - the ability to merge an index with moves rather
than copies. In some cases, you don't need/want to copy all the files and could just rename/move
them.
