Redis or MongoDB

I am also interested in this

Mee too, as I am using BOA Aegir, which has Redis installed and enabled by default.
Also, with (my personal) history of memcached beeing much less stable than APC - Radioactivity could have more than 1 backend to store data: APC, memcached, redis, mongo...

Actually the memcache storage class should serve as an example how to write a Redis/Whatnot storage.

It shouldn't be actually too hard to implement.

Crossing linking with task #1738388: Experience Using with the BOA / Aegir Project.

no news about redis/apc?

This would be a great feature

AFAICT, Redis support is available in the latest development version of the module.

As mentioned above, adding APC-support should be fairly simple by using the included Memcache class as a template.

I've created a quick-and-dirty patch which shows a way to add APC support to the module.

Dev version now has support for Redis, I will review the APC next

In addition to supporting Redis via the PhpRedis library, could the Predis library also be supported?

Attached is a patch to support both PhpRedis and Predis libraries for Redis access.

The patch also takes the Redis module settings as defaults for Radioactivity admin settings form and adds password authentication support for the connection with both libraries.

I've updated the above patch to set the Drupal root (since that was giving me watchdog errors in setPredisAutoload()) and to bootstrap the redis settings a little better. Works for us using PhpRedis.

updated patch as a git diff.
