[ccache] Using ccache with memcached

[Henrik Goldman]

Hello,

I wonder if anyone ever considered using memcached as an optional 
backend for ccached?

Here is the issue we're considering. In our C++ project we have a number 
of developers doing their own local compilations. When any updates 
occurs (e.g. they update to the latest source code from scm) the 
compilations are the same for all the machines. Sure ccache is great 
when you re-do the compilation, but here the compilation being re-done 
on a number of machines. Using memcached would allow us to have a truly 
distributed cache that would both help developers and machines in the 
build farm to speed up work.

What do you guys think?
