Docs: add API docs for batch processing utility

[dreamorosi]

What were you searching in the docs?

As a customer I should be able to consult the API docs for the new utility to understand the different components and how they work.

Is this related to an existing documentation section?

No response

How can we improve?

We should update the docstrings for each type, function, class, and method in the new utility.

Got a suggestion in mind?

No response

Acknowledgment

• I understand the final update might be different from my proposed suggestion, or refused.
