    Reusing macros promotes consistency and reduces maintenance overhead.

  3. Final Answer:

    To maintain consistency and reduce duplication across projects -> Option C

  4. Quick Check:

    Reusing code saves effort and ensures uniform logic [OK]
Quick Trick: Reuse macros to avoid duplication and ensure consistency [OK]
Common Mistakes:
MISTAKES
  • Thinking dbt forces all macros to be shared
  • Assuming macros from other projects run faster
