Understanding Coarse-Grained vs. Fine-Grained API Design:
A coarse-grained design consolidates multiple operations within a single API, leading to fewer APIs but with more complex implementations. Conversely, a fine-grained design breaks down functionalities into smaller, more specific APIs, resulting in simpler implementations but a larger number of APIs.
Evaluating the Options:
Option A (Correct Answer): With a coarse-grained design, each API handles more functionalities, increasing the complexity of each API implementation as it needs to manage more use cases and logic.
Option B: A coarse-grained design typically reduces the number of APIs, so fewer discoverable assets are available.
Option C: Fewer APIs generally mean fewer connections between them in the application network.
Option D: Network infrastructure usage may actually decrease with fewer APIs, as there are fewer calls between APIs.
Conclusion:
Option A is the correct answer, as the complexity of each API implementation increases in a coarse-grained design due to the consolidation of multiple functionalities into single APIs.
