Redis support

I would like to know that too!

some food for thought :
WordPress with Redis
and
Ludicrous Speed: WordPress Caching with Redis

I agree that it would be a good idea, either as an HTML cache like the above solutions or as an object cache, like the current memcache implementation.

It would also be great if the admin could choose between predis and the pecl redis extension.

According to the developer it’s on the roadmap. Hopefully they add Unix socket support.

Looking forward to this as well.
Hopefully we get an update soon.
