Descriptions of the changes in this PR: There is a user case. 1. They have two zones, they have a rack aware policy that ensures it writes across two zones 2. They had some data on a topic with long retention 3. They ran a disaster recovery test, during this test, they shut down one zone 4. During the period of the DR test, auto-recovery ran. Because the DR test only has one zone active, and because the default of auto-recovery is to do rack aware with the best effort, it recovered up to an expected number of replicas 5. They stopped the DR test and all was well, but now that ledger was only on one zone 6. They ran another DR test, this time basically moving data to the prod zone, but now data is missing because it is all only on one zone We should support a feature to cover this case. -- This is an automated message from the Apache Git Service.
