Using large Complex Data Types (CDTs) in a scenario where only a few fields are captured will likely result in increased overhead of capturing and modifying variables. Large CDTs inherently carry with them a larger amount of data structure and associated metadata, which means that even if only a small portion of their capacity is utilized, the system must still manage the full complexity of these data structures.

This increased overhead can manifest in several ways. First, there is additional memory usage, as the entire structure of the large CDT exists in memory even if only a fraction of it is needed. This can slow down processes that involve creating, updating, or retrieving data.

Moreover, the complexity of managing a large CDT means that any operations related to it, such as data extraction or alterations, could take longer to execute. Therefore, instead of a streamlined approach when interacting with only a few fields, a developer may find themselves dealing with unnecessary complexities and longer processing times.

In contrast, using smaller, more focused CDTs or even simple types when only a few fields are necessary can lead to more efficient data handling, simpler code, and improved overall system performance.
