["ramkrishna.s.vasudevan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-4322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15409799#comment-15409799 ] 

ramkrishna.s.vasudevan commented on FLINK-4322:
-----------------------------------------------

bq.jobs should be able to resume from checkpoint or savepoints
bq.jobs should fall back to the latest checkpoint or savepoint
Ya this is what FLINK-3397 tries to achieve too. 
[~uce] had given some comments and I had update the document but not yet uploaded in that JIRa. He was also telling about job and save point mapping. I had raised some comments and doubts regarding that in the other JIRA. As he is very busy just waiting for his inputs. As this and FLINK-3397 are related am happy to work on these and will do after we are arriving at a consensus on the design part. Thanks.

> The Checkpoint coordinator should have the functionality of both handling checkpoints and savepoints.
> The difference between checkpoints and savepoints is minimal:
>   - savepoints always write the root metadata of the checkpoint
>   - savepoints are always full (never incremental)
> The commonalities are large
>   - jobs should be able to resume from checkpoint or savepoints
>   - jobs should fall back to the latest checkpoint or savepoint
> This subsumes issue https://issues.apache.org/jira/browse/FLINK-3397
