             Summary: Allow CacheStores to access fields of data for which the schema is known
                 Key: ISPN-3660
                 URL: https://issues.jboss.org/browse/ISPN-3660
             Project: Infinispan
          Issue Type: Enhancement
          Components: Loaders and Stores
            Reporter: Tristan Tarrant
            Assignee: Mircea Markus


Currently cache stores read/write data from persistent storage as an opaque blob. Where we have access to the schema of data, we could expose this schema to the store so that it can write the single fields in a more appropriate fashion for the underlying persistence layer, e.g. write individual fields as columns in a relational database table or use the rich mapping of document stores (e.g. CouchDB, MongoDB).
Additionally, stores should also be able to do the same for the entry's metadata (e.g. version, etc), as is already done for expiration.

This technique can enable analysis / modification of data using the specific store tools (e.q. sqlplus, etc), or load pre-existing data to be served by the cache
