What is a significant reason for using numeric key fields in Qlik Sense?

Using numeric key fields in Qlik Sense is particularly advantageous because Qlik reads them much faster compared to string fields. This increased speed is due to the way numeric values are stored and processed in computer memory, as they require less computational resources compared to their string counterparts. Faster reading of these numeric fields can lead to improved performance during data loading and querying, ultimately enhancing the responsiveness of applications when users interact with data visualizations.

The choice concerning reduced app loading time can be influenced by various factors, including the overall data model and data volume. While managing numeric fields can be straightforward, the primary reason for their use leans heavily towards performance. Storage requirements are also important, but the efficiency of numeric key fields is fundamentally tied to how quickly Qlik can process them, which makes the choice of numeric keys a strategic decision in optimizing the data architecture within Qlik Sense.
