> I am caching some huge objects in a JCS disc cache. The objects are 3-15MB in serialized
size and there are a lot of them. The normal setup with a LRUMemoryCache and a IndexedDiskCache
works fine, but I would like to store as many objects in ram as possible without risking going
out of ram. To get to this goal I have created a SoftReferenceMemoryCache that is based on
a ConcurrentHashMap<Serializable, SoftReference<ICacheElement>>
> This task is to track the work and discuss this with others. Or perhaps get some feedback
that this is not a good idea.
