Thats good to know, i know you can set a max number of nodes on this but can you set a minimum? I have the scenario where if it goes past a certain time i.e its stale then ask data source for data however if data source is not available then use stale data. So does the expiration policy keep a minimum amount of stale data or will it purge all data that has gone past the expiration time? 


Now to get back to the main point, why it doesnt make sense to run CCL in LOCALMODE. Just referring back to the example given and the comment

That really a case if you cared about the state of data between the nodes. For my application, what defines whether to use the value, is the time duration. So I dont care what the value/state is as long as its not older than X mins old. If is older than Xmins old then a new value is retrieved.  
I do see that it breaks the concept of what a cache loader is if you were allowed to use CCL in LOCAL mode but i do think there is a need to have something like CCL in local mode.
