---------------------------------------------
Summary: Add a safety net for concurrent checkpoints on TM side
Key: FLINK-15236
URL: https://issues.apache.org/jira/browse/FLINK-15236
Project: Flink
Issue Type: Improvement
Components: Runtime / Checkpointing
Reporter: Congxian Qiu(klion26)
As discussed in FLINK-13808, we can add additional config
{{taskmanager.checkpoints.max-concurrent}} that limits the number of 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.
