             Summary: ntroduces savepoint mechanism of Table Store
                 Key: FLINK-31194
                 URL: https://issues.apache.org/jira/browse/FLINK-31194
             Project: Flink
          Issue Type: New Feature
          Components: Table Store
    Affects Versions: table-store-0.4.0
            Reporter: Nicholas Jiang
             Fix For: table-store-0.4.0


Disaster Recovery is very much mission critical for any software. Especially 
when it comes to data systems, the impact could be very serious leading to 
delay in business decisions or even wrong business decisions at times. Flink 
Table Store could introduce savepoint mechanism to assist users in recovering 
data from a previous state.

As the name suggest, "savepoint" saves the table as of the snapshot, so that it 
lets you restore the table to this savepoint at a later point in snapshot if 
need be. Care is taken to ensure cleaner will not clean up any files that are 
savepointed. On similar lines, savepoint cannot be triggered on a snapshot that 
is already cleaned up. In simpler terms, this is synonymous to taking a backup, 
just that we don't make a new copy of the table, but just save the state of the 
table elegantly so that we can restore it later when in need.
