-------------------------------------
{quote}By real world motivation, I meant if that really is an issue that
someone complained about?
{quote}
The reason behind this is some of our customers start their job with default
configuration and find out a back-pressure and checkpoint failures last for a
while. They reached out to me to ask if there is some way that can eliminate
the back-pressure without introducing much more delay or pouring much
duplicated data into sink (not exactly-once). What they complain is they must
suffer first to restart the job.

> Project: Flink
> Issue Type: New Feature
> Components: Command Line Client, Runtime / Checkpointing
> Reporter: Zakelly Lan
> Assignee: Zakelly Lan
> Priority: Major
>
> After FLINK-6755, user could trigger checkpoint through CLI. However I
> noticed there would be value supporting trigger it in unaligned way, since
> the job may encounter a high back-pressure and an aligned checkpoint would
> fail.
>
> I suggest we provide an option '-unaligned' in CLI to support that.
>
> Similar option would also be useful for REST api
