> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing
> Reporter: Congxian Qiu(klion26)
> Priority: Major
>
> As discussed in FLINK-13808, we can add additional config

> concurrent checkpoints on the TM for safety net.
> this configure {{taskmanager.checkpoints.max-concurrent}}, and the default
> value for maxConcurrentCheckpoints=1 is 1 and unlimited for
> maxConcurrentCheckpoints > 1.
> * If maxConcurrentCheckpoints = 1, the default
> {{taskmanager.checkpoints.max-concurrent}} is 1.
> * If maxConcurrentCheckpoints > 1 the default value for
> {{taskmanager.checkpoints.max-concurrent}}, is unlimited
> should not take manually triggered checkpoints/savepoints into account.
