Pramod Immaneni updated APEXMALHAR-2473:
----------------------------------------
Description: Currently db CacheManager has no knowledge of characteristics
of the data or the cache stores, so it handles all scenarios uniformly. This
may not be the optimal implementation in all cases. Better optimizations can be
performed in the manager if this information is known. A few examples, if the
data is read-only the keys in the primary cache need not be refreshed like they
are being done daily today, if the primary cache size is known the number of
initial entries loaded from backup needn't exceed it. Add support for such
general cache meta information in the manager. (was: Currently db
