medium📝 Predict Output Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Understand clustering requirements
Clustering columns must exist in the model's output; otherwise, the build fails.Step 2: Identify error behavior
If clustering column is missing, dbt raises an error during model compilation or build.Final Answer:
The model will fail to build with an error about missing clustering column -> Option CQuick Check:
Missing clustering column causes build error [OK]
Quick Trick: Clustering columns must be in model output or build fails [OK]
Common Mistakes:
MISTAKES- Assuming clustering silently ignores missing columns
- Thinking clustering applies to random columns
- Confusing clustering errors with partitioning errors
