Dynamically Loading Multiple Cache Instances
If configured, TimesTen can dynamically load multiple cache instances for dynamic cache groups that contain only a single table.
TimesTen Classic dynamically loads cache instances
            associated with a primary key that do not already exist in the cache group. Any cache
            instances associated with a primary key that already exist in the cache group are not
            reloaded. As a result, your query may return partial results. If a cache instance
            already exists on TimesTen, these cache instances can only be updated with either an
            autorefresh operation or a REFRESH CACHE GROUP statement.
