dbt - Production Deployment

You want to optimize your CI pipeline using Slim CI. Your previous run artifacts are stored in ./target/previous. You have models 'A', 'B', and 'C'. Only 'B' was modified. Which command will run only the modified model and also run its dependent models?

Adbt run --state ./target/previous --select state:modified

Bdbt run --state ./target/previous --select state:modified --full-refresh

Cdbt run --state ./target/previous --select state:modified+

Ddbt run --select state:modified --state ./target/previous --exclude B

Step-by-Step Solution

Solution:

Step 1: Understand the '+' operator in selection
The '+' after state:modified selects modified models plus their dependents.
Step 2: Match command to requirement
dbt run --state ./target/previous --select state:modified+ uses state:modified+ with correct --state path, running 'B' and its dependents.
Step 3: Evaluate other options
dbt run --state ./target/previous --select state:modified runs only modified models without dependents; C adds unnecessary full-refresh; D excludes 'B' incorrectly.
Final Answer:
dbt run --state ./target/previous --select state:modified+ -> Option C
Quick Check:
Modified plus dependents run [OK]

Quick Trick: Add '+' to include dependents of modified models [OK]

Common Mistakes:

MISTAKES

Not including dependents with '+'
Using --full-refresh unnecessarily
Excluding modified models by mistake
