Explanation:
The Pipeline Manager is a system that executes a series of processors, which are
linked in processor chains. A processor is a component that executes a piece of functionality and

returns a status code. The status code determines which processor in the chain to execute next.
The Pipeline Manager enables you to dynamically add and remove processors and chains of
processors.
