--------------------------------------
Hi [~ivanandika]
I've drafted a design document proposing a {{{}SequenceId{}}}-based incremental
replication approach to address this issue.
It covers the required wire protocol changes ({{{}fromSequenceId{}}}), delta
export/import logic, and backward compatibility.
PR for the design doc: [https://github.com/apache/ozone/pull/9913]
Any feedback or suggestions would be greatly appreciated before the actual
implementation.
Thanks!

> If two container replicas have two different sequence ID, we can setup
