vinoyang commented on FLINK-6755:
---------------------------------
[~klion26] The considerations facing this issue also exist in your FLINK-12619,
if you read the comments again. In fact, stop-with-checkpoint is just one of
the special cases of triggering checkpoints manually. This is why I ping you
and [~aljoscha]. Of course, I agree with your worry about "vulnerabilities",
but this also exists in savepoint.
I agree with [~gyfora] 's point of view, I think we need to seriously consider
the needs that users really care about. If this feature is truly valuable to
users, we don't have to wait for a long release cycle. Of course, I am not
saying that the problems facing the moment are not important, but they are
already there, and we can also push it together to see how to solve them.
> 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.
