[infinispan-dev] refresh ahead - do we want this?

For example, assume that the expiration time for entries in the cache is set to 60 seconds and the refresh-ahead factor is set to 0.5. If the cached object is accessed after 60 seconds, a synchronous read from the cache store is performed to refresh its value. On the other hand, if a request is performed for an entry that is more than 30 but less than 60 seconds old, the current value in the cache is returned and an asynchronous reload from the cache store is scheduled. For frequently accessed data, requests won't block waiting for data to be retrieved from persistent store if data expires. Wdyt? Cheers, Mircea
