---------------------------------
Hi [~till.rohrmann] If you don't mind, I want to invite [~gyfora] to be my
mentor to implement this issue. We try to implement minimal changes. As for the
side effects that have always existed, we hope to solve it at some point in the
future. Maybe we can temporarily not provide the stop-with-checkpoint function.
What do you think?
> 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.
