Hi Edward,
I think the key problem is not making it up to date, but copy the
information of the sequence. Thinking about the following example:
we say source have seq node /test5.
Then I copy it to destination cluster, but create a non-seq node instead.
After some while, the other application switch to destination cluster, and
continue create seq node /test.
When the seq no is 5, it will fail when create the node and the application
may be blocked or failed.
Since I could not know if the node is seq one only according to the api, I
could not create a seq node in destination cluster.
Thanks,
Gang
