@JG Aside above tow features, I am considering following framework:
Sometimes, we want to modify/update a cell value, but the update depends on the current value. IIRC, it is very slow when read+update+write (GET+UPDATE+WRITE). De you think this requirement is reasonable? Maybe we can provide a programming framework in client API, to let the user of client API provide user-defined operations. For example, one cell's current value is a integer 100, and the user want to increase 1, the user can provide a user-define class and serialize and send to RS, then the RS can do the operation on this cell.
