Hello List, I have to questions concerning the same question: I would like to cache the results of expensive PythonScript calls using a persistent, non-undoable storage. At the Moment, I'm using a RAMCacheManager, but this solution is suboptimal for my special case. Firstly, the generation can take quite long for some objects and I want to avoid having to regenerate all the data after restarting zope. Secondly the amount of data to be cached is pretty large and might grow to several 100 MB, so a RAMCacheManager is certainly *not* the way to go. I could implement a specialized Produkt for this need but would prefer a general solution to above scenario. So the concrete Questions: * Does anyone know of a CacheManager implementation, which stores its data in persistent storage? This might be ZODB (but the Product should make shure, it doesn't cause ZODB-Bloat on every cache hit) or some other persistent disk-based storage (explizit files in the Instance home or whatever) * researching for non-undoable ZODB storage implementations, I could only find discontinued or incomplete solutions. Is there such a beast for current (2.7) Zope installations? Thanks for any help ... and please reply on-list, otherwise I will never see your reply (see the signature...)
