Data Storage

All data put to a global cache is stored in a persistent backend datastore on the Broker’s file system. You can limit the size of the Broker’s file cache. The default is that there is no limit. If the Broker’s file cache is size limited and full, the Broker silently removes data to make room for the incoming data. If the cache entry is too big, it first goes to the memory cache, and if it cannot fit there it goes to the disk cache. If it is too big for the disk cache too, then it is dropped. There is no global resilience when using a memory-based cache; however, you can use a loader for that purpose.
