By employing parameterized pipelines, these object names and behaviors can be read from the control table and applied to the jobs accordingly. “Copy behaviors” refer to the specific actions or configurations associated with copying each object. These behaviors can include parameters such as source and destination locations, data transformation requirements, scheduling preferences, error-handling strategies, and any other settings relevant to the copying process.

Unlike traditional methods that require redeploying pipelines whenever the objects list needs modification (e.g., adding or removing objects), utilizing a control table allows for swift and straightforward updates...
