Using MySQL Query Cache and Memcached at the same time

I think they are both great and I wanna know is it possible to use both caching systems together at the same time? Is there any experience?

Solution

  • Mysqls working set will always be cached.

    This is called double caching and represents a major bottleneck in larger systems (Facebook for example), where user data is double cached, existing twice in RAM.
