The MOST CRITICAL consideration when designing the enrichment logic, especially under strict project constraints, involves a balanced approach that evaluates the accuracy and relevance of the additional data in the context of the existing dataset. Additionally, assessing the impact on data storage and performance ensures the enrichment process is cost-efficient, accurate, and scalable. This approach aligns with the project's requirements and avoids the pitfalls of focusing on only one aspect at the expense of others, such as minimizing costs without regard for data accuracy or prioritizing speed over scalability and accuracy.
