Till Rohrmann commented on FLINK-6755:
--------------------------------------
The idea of checkpoints are that they under control of Flink. In contrast to
that savepoints are user realm objects which need to be explicitly managed by
the user. I'm not sure whether we should leak the concept of checkpoints by
introducing this feature even though I can see the benefit of it.
At some point there was also the idea to support incremental savepoints. Not
sure, whether this is feasible, though.
> Allow triggering Checkpoints through command line client
> --------------------------------------------------------
>
> Key: FLINK-6755
> URL: https://issues.apache.org/jira/browse/FLINK-6755
> Project: Flink
> Issue Type: New Feature
> Components: Command Line Client, Runtime / Checkpointing
> Affects Versions: 1.3.0
> Reporter: Gyula Fora
> Assignee: vinoyang
> Priority: Major
>
> The command line client currently only allows triggering (and canceling with)
> Savepoints.
> While this is good if we want to fork or modify the pipelines in a
> non-checkpoint compatible way, now with incremental checkpoints this becomes
> wasteful for simple job restarts/pipeline updates.
> I suggest we add a new command:
> ./bin/flink checkpoint <jobID> [checkpointDirectory]
> and a new flag -c for the cancel command to indicate we want to trigger a
> checkpoint:
> ./bin/flink cancel -c [targetDirectory] <jobID>
> Otherwise this can work similar to the current savepoint taking logic, we
> could probably even piggyback on the current messages by adding boolean flag
> indicating whether it should be a savepoint or a checkpoint.
