Zakelly Lan commented on FLINK-33897:
-------------------------------------

This also require the {{SingleCheckpointBarrierHandler}} changing from aligned to unaligned state when receiving an unaligned barrier. Would like to hear your thoughts [~pnowojski] [~dwysakowicz]

> 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
