Abstract
A write log that distinguishes between write operations that are known to be in a stable write order ("committed writes") and write operations that still are in a potentially unstable write order ("tentative writes") are maintained for each instance of a weakly consistent replicated database so that the stable and the potentially unstable data in any given instance of such a database can be explicitly identified.
