> Key: HBASE-10711
> URL: https://issues.apache.org/jira/browse/HBASE-10711
> Project: HBase
> Issue Type: New Feature
> Components: Admin, shell
> Affects Versions: 0.94.17
> Reporter: Rekha Joshi
> Assignee: Rekha Joshi
>
> In parallel to SQLWorld, Hbase needs to have easy feature to
> savepoint/rollback/commit.
> This functionality can help retrieve table state before a set of commands are
> executed.Especially if one inadvertently drops a table, rollback is a
> lifesaver.
> SAVEPOINT < savepoint_name >;
> ROLLBACK [TO SAVEPOINT < savepoint_name>];
> COMMIT;
> This internally will take a snapshot of table(s) when a command 'savepoint'
> is executed on hbase shell/api.Each savepoint takes the snapshot , and stores
> the map with savepoint id to snapshot taken.Will need a retrieval from the
> last-est savepoint id.
> Given that it might take some time, this savepoint is the users option if one
> is into too many operations and one operation goes wrong, they can still
> start from save point.For better perf, it would be nice to provide command
> set tables 'a','b','c' and the savepoint command then takes the snapshots of
> only those tables rather than all.
> Maybe i am a burnt child dreading the fire, but thoughts?
