> My follow-up question is actually that there seems still some potential inconsistency issue here not addressed, namely across controllers over different machine. > > The pattern is similar to this #1066. > > If one controller session expired, and super controller assign another controller to take care the cluster. When first controller come up, his controller pipeline may still run and persists his baseline and best possible again. How do we guard this across java process race condition? > > This is a pattern of similar problems. We should think a little bit more generic and address them all long term. Please note that we have an MVCC implemented in the bucket accessor to ensure cross node consistency. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
