Hi, guysI have some problem about index server driver.1) How does driver know excutor’s data distribution? How does the driver choice the executor to work?2) From the design document it seems that under the index cache server index data store under each executor, there is no need for Use of Cache Layer.3) Under carbon driver, if index cache server failure we need to reuse driver side cache. If we can abstract driver side cache into a cache layer?
