In a distributed program, how to recovey its corresponding data when a process crashes

Question

I have a distributed program, for example, it has ten process, and all of them will execute some job, all job info will storage to a same MySQL database. At a same moment, there was a lot of running job in database, and they are belong to different process. When one process crash, how can I recovery it running job info in a new process. By the way, my enviroment has MySQL and zookeeper.

That depends on the nature of the jobs. Edit the question to add more details. — root, Dec 04 '20 at 05:14
