Using Isolated and In Memory Caching

Topics: Caching Application Block

Hi All,

I'm looking at the caching application block particularly for its isolated storage.  I implemented a cache of my own for a smart client that pulls back large amounts of data from an analysis services cube.  I'm starting to use too much memory on the client though so I thought the caching application block might help.  Can you configure the caching application block with in memory limits while still storing everything you want in the isolated storage? I couldn't tell from the reading so far  but what I really need is an in memory cache where part of it can be dumped to isolated storage when the memory limit is hit, but I still want to pull those pieces back into memory at a later time withouth going back to the cube.  Does anyone know if this can be accomplished using the enterprise library cache?

Thanks for any help,

Shane

You would need to add 2 CacheManagers in your configuration.  If you add the Caching Application Block to your configuration, it will automatically have a CacheManager.  Add another one and configure it to use an IsolatedStorage.  Each CacheManager has a MaximumElementsInCacheBeforeScavenging property which you can set to limit the number of items in a cache.  You can compare the Count property of the CacheManager against this property to allow you to decide where to cache the item.
