> With Unaligned checkpoints, happens always (new checkpoint is never started or triggered).
> With Aligned checkpoints - to some degree - depending on state size and thresholds: delayed by 1 minute. Delay grows very slowly with state size.
>  
> Filesystems: s3p and s3a
> Parallelism: 176, repartition (num stages): 5.
> Number of files in checkpoint is about 1K (depends on state.backend.fs.memory-threshold and their size). Size doesn't matter (100K..10G).
