Otto Fowler commented on VFS-654:
---------------------------------
WatchEvent is very cool. The Java ( 7+) system is very similar to VFS, in that
there is a provider spi for supporting file systems. I am not sure what
providers are installed on what operating systems. On my mac, I only have the
OSX and ZIP installed.
So, to support WatchEvent for any local filesystem would seem to be possible.
For other filesystems that VFS supports, it would depend on what providers
where loaded, therefore these would become dependencies.
INotify for hdfs could be implemented on it's own as well.

> File system events API
> ----------------------
>
> Key: VFS-654
> URL: https://issues.apache.org/jira/browse/VFS-654
> Project: Commons VFS
> Issue Type: New Feature
> Affects Versions: 2.2
> Reporter: Boris Petrov
> Priority: Major
>
> Currently the DefaultFileMonitor walks the whole file system and notifies
> when something changes. For large file systems and (near) real-time
> requirements this is _extremely_ inefficient. Some file systems have an
> events API which could be exposed (like *inotify*). Has any work towards that
> ever been done?
