Steven Zhen Wu commented on FLINK-17421:
----------------------------------------
what does "backpressure new checkpoints" mean? are we suggesting delaying the
triggering of the next checkpoint.
In our setup, we only allows one concurrent checkpoint. I assume that this
potential change doesn't matter to us?
> Backpressure new checkpoints if previous were not managed to be cleaned up
