> 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.
