Ah, now I understand what exactly your requirement is. I don't think there is such a tool in Flink which could help you to fetch and store the content of rest api. It seems not to be a general requirement.
But I'm really interested in the motivation behind your requirement. Could you share more about it? Why do you want to keep the history of checkpointing at subtask level? How do you use this history?
