dbt - Performance Optimization
Which dbt feature allows multiple models to run at the same time when they have no dependencies between them?
Which dbt feature allows multiple models to run at the same time when they have no dependencies between them?
easy🧠 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify feature for concurrent execution
Parallelism means running multiple tasks simultaneously when they don't depend on each other.Step 2: Match with dbt features
In dbt, parallelism controls how many models run at once if they have no dependencies.Final Answer:
Parallelism -> Option BQuick Check:
Parallelism = concurrent runs [OK]
Quick Trick: Parallelism runs independent models simultaneously [OK]
Common Mistakes:
MISTAKES- Confusing parallelism with incremental loading
- Thinking snapshots control parallel runs
- Mixing materializations with execution concurrency
