> Add directory wrapper that optionally uses hardlinks in copyFrom
> ----------------------------------------------------------------
>
> Key: LUCENE-7300
> URL: https://issues.apache.org/jira/browse/LUCENE-7300
> Project: Lucene - Core
> Issue Type: Improvement
> Affects Versions: 6.1
> Reporter: Simon Willnauer
> Assignee: Simon Willnauer
> Fix For: 6.1, master (7.0)
>
> Attachments: LUCENE-7300.patch, LUCENE-7300.patch
>
>
> Today we always do byte-by-byte copy in Directory#copyFrom. While this is
> reliable and should be the default, certain situations can be improved by
> using hardlinks if possible to get constant time copy on OS / FS that support
> such an operation. Something like this could reside in misc if it's contained
> enough since it requires LinkPermissions to be set and needs to detect if
> both directories are subclasses of FSDirectory etc.
