Hi Zhen Peng Cai,
please see my technical explanation in the other forum thread (#208319). Having briefly read through the documentation on Velocity it appears to me that our cache concepts do not match 100%. DataAccess uses an in-memory-in-process cache, where Velocity uses a in-memory-separate-process cache. Changing our cache implementation is not trivial and might actually prove counterproductive to performance. There is no plan to open up the internal APIs needed for such undertaking.
