-----------------------------------
We've decided not to put this in Hive since there is no other use case in Hive
now.

> Although the current implementation for validWriteIdList is not strictly
> immutable, it is in some sense to provide a read-only view snapshot. This
> change is to add another class to provide functionalities for manipulating
> the writeIdList. We could use this to keep writeIdList up-to-date in an
> external cache layer for event-based metadata refreshing.
