The role of the chassis is to accept the power of the engine, so that the wheel rotates, and to ensure that the car according to the driver's control normal driving. The chassis includes the four parts of the drive system, the driving system, the steering system and the braking system, usually referred to as the driveline, drive train, steering and braking systems. The suspension is the general term of the transfer force connection between the frame and the axle, and its function is to transfer

Therefore, if you use persistence as a savepoint as a filesystem jobmanager checkpoint, Flink will not be implemented in this case fault tolerance because the job manager checkpoint data will not be accessible after the reboot. Therefore, it is best to ensure the consistency of two mechanisms.Flink SavepointStoreFactory#createFromConfig creates a specific implementation by combining the configuration file StateStore .SummaryIn this paper, we mainly
