Chicago Taxi data ingestion project

This project builds a data pipeline for loading the Chicago taxi trips dataset into BigQuery for subsequent analysis.

Project Steps:

1. Terraform: Create a bucket in GCP and a dataset in BigQuery.
2. AirFlow: Pipeline for loading data into the bucket and subsequently creating an external table in BigQuery.
3. dbt: Create models for use in subsequent analysis.

Terraform docs

Before Running Terraform

You need to:

• configure a service account in GCP
• install Google Cloud SDK
• authenticate in GCP
• install Terraform

To create the infrastructure, run the following script:

bash run_terraform.sh

Check what it is going to do and press yes.

Airflow docs

Before Running the Docker Container with Airflow

You need to place the Google credentials in the ~/.google/credentials/ directory on your machine (either local or VM).

cd ~ && mkdir -p ~/.google/credentials/
mv <path/to/your/service-account-authkey>.json ~/.google/credentials/google_credentials.json

Before running the container, remember to update:

• the GCP_PROJECT_ID and GCP_GCS_BUCKET variable values in the .env file
• the DOWNLOAD_START_DATE, DOWNLOAD_END_DATE, BIGQUERY_DATASET, TABLE_ID variable values in dag__data_ingestion.py

Execution:

1. Run the following command to build an image, initialize Airflow, and kick up all services:

bash run_airflow.sh

2. Login to Airflow web UI on localhost:8080 with default credentials admin/admin and run DAG named dag__data_ingestion

3. To shutdown all Airflow services run:

bash shutdown_airflow.sh

dbt docs

Before running models please install dbt-core or set up dbt cloud. For more details, refer to the official documentation

Commands to run dbt models:

dbt seed
dbt build
