Execution: JobInstance, JobExecution,
and StepExecution The state of a job is broken down into various parts, and persisted in the repository – Submitting a job creates a JobInstance, a logical representation of a particular “run” of a job. – A JobExecution is a single attempt to run a JobInstance. A restart attempt creates another JobExecution – Similarly, a StepExecution is a single attempt to run a step within a job. It is created when a step starts execution.
