I'm risking showing lack of understanding, but I think it would be really nice to have some kind of a redis API that allows archiving certain keys (to disk). Perhaps the same way that keys can EXPIRE, they can get archived into secondary storage. Another API would allow retrieving keys from secondary storage.

Of course you can do this in your code, but then you step out of redis. I think it would be nice to bake this into redis, knowing that once loaded back from secondary storage, you get exactly the same object, and avoiding the whole (de)serialization process. Of course you won't achieve the same performance, but this is at least a known penalty.




We already have what you described in Redis 2.6: DUMP and RESTORE commands :-)


Dude. This is awesome. Sorry for my severe RTFM deficiency.

I'll go and play with this now... :)
