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.
