Re: [Wikidata-tech] alternatives to memcached for caching entity objects across projects

Hey, We use two CachingEntityRevisionLookup nested into each other: the outer-most uses a HashBagOStuff to implement in-process caching, the second level uses memcached. It is odd to have two different decorator instances for caching around th EntityRevisionLookup. I suggest to have only a single decorator for caching, which writes to a caching interface. Then this caching interface can have an implementation what uses multiple caches, and perhaps have a decorator on that level.
