Or perhaps you don't need to remove all the items and are just hacking round a more targeted removal strategy? How do I access the underlying memory cache to dispose it and instantiate a new one?To get the most benefits from the cache, it is best not to throw away all the data stored in it if you can. Seems there is no properties "keys" or "memorycache" that I can use for a "foreach" loop. Cheers You would need to either create an instance of Memory Cache yourself and pass it into the Lazy Cache constructor to have access to the instance, or use Memory Cache.If you are into serverless, today is your lucky day!I can remove an cache item, but how do I clear the whole cache.A cache in front of Dynamo DB is boosting performance and saving costs. But setting up cache invalidation is not that hard when using the following building blocks: Elasti Cache, Dynamo DB, Dynamo DB Streams and Lambda as shown in the following figure.Especially true for read-intensive and spiky workloads. Please have a look at one of my recent articles: Performance boost and cost savings for Dynamo DB.

Hello, got your new version and tried to dispose the cache by using the new Object Cache property. Maybe this is useful for a new version of Lazy Cache.From my understanding this is not possible, because the class "Object Cache" is abstract and cannot be used in any way. ( So now I just want to remove all items of instance cache1.Without caching, your application must request the data from the database each time a user wants to view a product.You could cache the product information for a day at a time, ensuring fast response times because the product information is already in memory.
