dbt - Performance Optimization

Consider these dbt models and their dependencies:

alpha.sql (no dependencies)
beta.sql (depends on alpha)
gamma.sql (depends on alpha)
delta.sql (depends on beta and gamma)

If dbt is run with --threads 2, which models will start running simultaneously?

Abeta and gamma

Balpha only

Cdelta only

Dbeta and delta

Step-by-Step Solution

Solution:

Step 1: Identify models with no dependencies
Only alpha.sql has no dependencies and can run immediately.
Step 2: Understand parallelism limit
With --threads 2, up to 2 models can run simultaneously, but only models without unmet dependencies can start.
Final Answer:
alpha only -> Option B
Quick Check:
Only alpha has no dependencies and can start immediately. [OK]

Quick Trick: Only models without dependencies start first [OK]
