> The current JDBC {{CacheStore}} implementation has the following shortcomings:
> * poor support for vendor specific queries (e.g. MySQL's replace into)
> * complex configuration is required to support the key types that cannot be converted to a String easily.
> To address this issue:
> * Introduce a single unified JDBC {{CacheStore}} implementation.
> * Support an arbitrary key type as long as it can be serialized via {{Marshaller}}.
> * Support both text and binary key.
> * Encode the binary key into a text key using an efficient text encoding if the target database doesn't support binary key column.
> * Provide much more flexibility in supporting vendor specific extensions. Let the user extend our {{CacheStore}} implementation and override the DB access (no more TableManipulation).
> Once implemented, the existing JDBC {{CacheStore}} could be deprecated.
> Configuring this would be, for example, {{GenericJdbcCacheStore}} which would have no vendor-specific optimisations, and {{MySqlJdbcCacheStore}} (subclasses {{GenericJdbcCacheStore}}) which would contain MySQL specific optimisations, etc.
