Execution Sample

dbt

models/my_model.sql
-- SQL select statement

-- Commit and push to Git

-- Trigger dbt Cloud job

-- Review job logs and results

This code snippet represents the steps from writing a dbt model to triggering a deployment job in dbt Cloud.

Execution Table

Step	Action	Input/Trigger	Process	Output/Result
1	Write dbt model	SQL file with select statement	Create model file in project	Model file ready for version control

Key Moments - 3 Insights

Why do we need to push code to a remote repository before triggering a dbt Cloud job?

Because dbt Cloud pulls the latest code from the remote repository to run the models. Without pushing, dbt Cloud won't see your changes (see execution_table step 3 and 4).

What happens if the dbt Cloud job fails during model run?

The job logs will show errors and the deployment status will be failure. You need to fix the errors and rerun the job (see execution_table step 6 and variable_tracker dbt Job Status).

Is the model immediately updated in the warehouse after writing the SQL file?

No, the model is only updated after the dbt Cloud job runs successfully and deploys changes (see variable_tracker Model File and Deployment Status).

Visual Quiz - 3 Questions

Look at the execution_table at step 4, what triggers the dbt Cloud job?

A Writing the SQL model file

B Manual or scheduled trigger

C Committing code locally

D Pushing code to remote repository

💡 Hint

Check the 'Input/Trigger' column in execution_table step 4

According to variable_tracker, what is the status of 'Git Push' after step 3?

A None

B Created

C Done

D Queued

💡 Hint

Look at the 'Git Push' row and 'After Step 3' column in variable_tracker

If the dbt Cloud job fails at step 6, what should you do next?

A Fix errors and rerun the job

B Write a new model file

C Push code again without changes

D Ignore and deploy anyway

💡 Hint

Refer to key_moments about job failure and execution_table step 6

Concept Snapshot

dbt Cloud deployment flow:
1. Write SQL models

6. Deploy changes if successful
Push code so dbt Cloud can access latest models.

Full Transcript

dbt Cloud deployment starts by writing SQL models. These models are saved as files. Next, you commit these changes locally using Git, then push them to a remote repository. dbt Cloud accesses this remote repo to get the latest code. You then trigger a dbt Cloud job manually or by schedule. The job runs your models by compiling and executing SQL in your data warehouse. After the run, you check the job logs for success or errors. If successful, your models are deployed and updated in the warehouse. If errors occur, you fix them and rerun the job. This process ensures your data models are version controlled and deployed safely.

Practice

1. What is the main purpose of dbt Cloud deployment?

easy

A. To automate running data transformations in the cloud

B. To write SQL queries manually every time

C. To store raw data without processing

D. To create dashboards for data visualization

Solution

1. Step 1: Understand dbt Cloud deployment

   dbt Cloud deployment is designed to automate the running of data transformation commands in a cloud environment.

2. Step 2: Compare options with purpose

   Only To automate running data transformations in the cloud describes automation of data transformations in the cloud, which matches the main purpose.

3. Final Answer:

   To automate running data transformations in the cloud -> Option A

4. Quick Check:

   dbt Cloud deployment = automate transformations [OK]

Hint: Remember: dbt Cloud runs your data jobs automatically [OK]

Common Mistakes:

• Confusing deployment with manual query writing
• Thinking dbt Cloud is for raw data storage only
• Mixing deployment with visualization tools

2. Which of the following is the correct way to schedule a job in dbt Cloud UI?

easy

A. Upload SQL files to the cloud storage

B. Write a Python script to run dbt commands

C. Manually run dbt commands every hour

D. Set a cron expression to run commands automatically

Solution

1. Step 1: Identify scheduling method in dbt Cloud

   dbt Cloud UI allows scheduling jobs using cron expressions to automate command runs.

2. Step 2: Eliminate incorrect options

   Options B, C, and D do not describe scheduling via the UI; only "Set a cron expression to run commands automatically" correctly describes cron scheduling.

3. Final Answer:

   Set a cron expression to run commands automatically -> Option D

4. Quick Check:

   Scheduling in dbt Cloud = cron expression [OK]

Hint: Scheduling uses cron expressions in dbt Cloud UI [OK]

Common Mistakes:

• Confusing manual runs with scheduled jobs
• Thinking Python scripts are needed for scheduling
• Assuming uploading files schedules jobs

3. Given this dbt Cloud job configuration:

commands:
  - dbt run
schedule: '0 2 * * *'

What does this job do?

medium

A. Runs dbt seed command once a week

B. Runs dbt tests every hour

C. Runs dbt transformations every day at 2 AM

D. Runs dbt run command manually

Solution

1. Step 1: Interpret the schedule cron expression

   The cron '0 2 * * *' means the job runs daily at 2:00 AM.

2. Step 2: Identify the command being run

   The command is 'dbt run', which runs data transformations.

3. Final Answer:

   Runs dbt transformations every day at 2 AM -> Option C

4. Quick Check:

   dbt run + daily 2 AM = Runs dbt transformations every day at 2 AM [OK]

Hint: Cron '0 2 * * *' means daily at 2 AM [OK]

Common Mistakes:

• Misreading cron schedule as hourly or weekly
• Confusing 'dbt run' with 'dbt test' or 'dbt seed'
• Assuming manual run instead of scheduled

4. You set up a dbt Cloud job with this schedule:

schedule: '60 2 * * *'

What is the problem with this schedule?

medium

A. The hour value 2 is invalid in cron syntax

B. The minute value 60 is invalid in cron syntax

C. The schedule runs too frequently

D. There is no problem; it is valid

Solution

1. Step 1: Check cron minute value

   Cron minutes must be between 0 and 59; 60 is invalid.

2. Step 2: Check cron hour value

   Hour 2 is valid (0-23), so the problem is the minute value.

3. Final Answer:

   The minute value 60 is invalid in cron syntax -> Option B

4. Quick Check:

   Cron minute max = 59, 60 invalid [OK]

Hint: Cron minutes max 59, hours max 23 [OK]

Common Mistakes:

• Focusing on the hour value instead of the minute
• Assuming schedule is valid without checking ranges
• Thinking frequent runs cause syntax errors

5. You want to deploy a dbt Cloud job that runs tests after transformations finish successfully. Which setup achieves this?

hard

A. Create two jobs: one runs 'dbt run', second runs 'dbt test' triggered after first succeeds

B. Create one job with commands: 'dbt test' then 'dbt run'

C. Schedule 'dbt run' and 'dbt test' to run at the same time

D. Run 'dbt test' only, skipping 'dbt run'

Solution

1. Step 1: Understand job dependencies

   Tests should run only after transformations succeed to validate results.

2. Step 2: Setup jobs with triggers

   Creating two jobs with the second triggered after the first ensures correct order.

3. Step 3: Eliminate incorrect options

   Create one job with commands: 'dbt test' then 'dbt run' runs tests before transformations, C runs both simultaneously, D skips transformations.

4. Final Answer:

   Create two jobs: one runs 'dbt run', second runs 'dbt test' triggered after first succeeds -> Option A

5. Quick Check:

   Test after run = two jobs with trigger [OK]

Hint: Use job triggers to run tests after transformations [OK]

Common Mistakes:

• Running tests before transformations
• Scheduling jobs to run simultaneously
• Skipping transformations before testing
