Redis Swapping?

Question

based on this screen shot: http://www.dropmocks.com/mBvx1

does redis need twice the memory I actually think it does? I believe it spawns another process to save to disk, does that mean it actually copies the memory and I should always assume if I have 16 gigs of ram 8 is the max for a single redis process?

Answer 1

I dont think Redis should be taking up ~8GB. You might want to upgrade to 2.X because I think you might have a memory leak.

But, back to your question, I think Redis does create a new process to save to disk, but Redis is stored in memory. It saves to disk in case of power failure resulting in loss of all data in the RAM
