In the Prod environment, there are some issues with query performance and you have identified that you need to alter the existing cluster key with new columns, as part of this same release you have dropped some columns on which the previous clustery key was defined, the changes were successfully deployed and the query performance with the new cluster keys is as expected. After two weeks of the deployment, there are some issues and you have to revert the changes. But the DBA team has Informed you that using Time Travel feature you can get the data snap shot as of a particular time but the dropped columns have to be manually restored. How would you resolve this prod issue at the earliest?
