If the component manages any internal state, its important that it be StepScope based so that one thread does not impair the state managed by another thread (e.g, each thread of a given step has its own instance of the StepScope component).
What is a Spring Batch stepscope object?
A spring batch StepScopeobject is one which is unique to a specific step and not a singleton. As you probably know, the default bean scope in Spring is a singleton.
