Which of the following statements is incorrect?

The correct statement emphasizes that Custom Classification is considered a scalable solution for many data streams. This approach allows you to organize data effectively by defining categories that can adapt to increasing volumes and various data sources. Scalability in this context means that as the amount of data increases, Custom Classification can accommodate new entries and maintain performance without significant degradation.

By leveraging a structured classification system, organizations can manage complex datasets and derive insights more efficiently. The inherent design of Custom Classification promotes ease of updates and modifications, making it suitable for environments where data is constantly evolving.

In contrast, the other statements highlight different aspects of performance or scalability that may not accurately represent their intended benefits or limitations. For instance, the mention of Calculated Dimensions and Data Fusion queries is crucial because while they provide real-time calculations, they may face performance issues under high data volumes, which could affect user experience. However, Custom Classification is structured specifically to handle a variety of data without suffering the same performance penalties, maintaining efficiency as demands grow.
