> Most of the changes are trivial, due to static changing to non-static. The 
> patch basically adds lifecycle management for shared cache, and uses it to 
> move prewarm to background thread, waiting for prewarm to happen at use time 
> not setConf, and to make init optional (if not called, CachedStore would 
> proxy the methods to rawStore, like it currently does in the ones not 
> implemented).
