Windows Azure Caching is described as distributed, but the documentation states that the high availability feature is unavalable and that the maximum cache size is 4GB.
The question is: is it possible to go over the 4GB size by creating a cluster of several caches, each 4GB in size? Or is 4GB the hard limit, and that 4GB is already clustered, supposedly of smaller caches?
You can have more than one cache. I just tested by creating two namespaces ‘gregolivera’ and ‘gregoliverb’.
Each cache namespace is managed separately, so this does not allow for creation of objects >4gb in size. Objects will not ‘bridge’ between caches.
