Loading Data from Fivetran to CockroachDB with dlt in Python

tip

We will be using the dlt PostgreSQL destination to connect to CockroachDB. You can get the connection string for your CockroachDB database as described in the CockroachDB Docs.

Loading data from Fivetran to CockroachDB using the open-source Python library dlt is a straightforward process. Fivetran is an ETL tool that helps customers leverage their data for AI applications, ML models, predictive analytics, and operational workloads. CockroachDB offers a simple, reliable SQL API and is a distributed, cloud-native database compatible with Kubernetes. It is also free up to 5GB and 1vCPU. By utilizing dlt, you can efficiently transfer data from Fivetran to CockroachDB, ensuring a seamless and scalable data pipeline. For more details on Fivetran, visit https://www.fivetran.com/.

dlt Key Features​

  • Scalability via iterators, chunking, and parallelization: dlt offers scalable data extraction by leveraging iterators, chunking, and parallelization techniques. This approach allows for efficient processing of large datasets by breaking them down into manageable chunks. Read more
  • Implicit extraction DAGs: dlt incorporates the concept of implicit extraction DAGs to handle the dependencies between data sources and their transformations automatically. This ensures data consistency and integrity. Read more
  • Automated maintenance: With schema inference and evolution, alerts, and short declarative code, maintenance becomes simple. Learn more
  • Governance support: dlt pipelines offer robust governance support through pipeline metadata utilization, schema enforcement and curation, and schema change alerts. Learn more
  • User-friendly, declarative interface: dlt provides a user-friendly, declarative interface that removes knowledge obstacles for beginners while empowering senior professionals. Learn more

Getting started with your pipeline locally​

OpenAPI Source Generator dlt-init-openapi

This walkthrough makes use of the dlt-init-openapi generator cli tool. You can read more about it here. The code generated by this tool uses the dlt rest_api verified source, docs for this are here.

0. Prerequisites​

dlt and dlt-init-openapi requires Python 3.9 or higher. Additionally, you need to have the pip package manager installed, and we recommend using a virtual environment to manage your dependencies. You can learn more about preparing your computer for dlt in our installation reference.

1. Install dlt and dlt-init-openapi​

First you need to install the dlt-init-openapi cli tool.

pip install dlt-init-openapi

The dlt-init-openapi cli is a powerful generator which you can use to turn any OpenAPI spec into a dlt source to ingest data from that api. The quality of the generator source is dependent on how well the API is designed and how accurate the OpenAPI spec you are using is. You may need to make tweaks to the generated code, you can learn more about this here.

# generate pipeline
# NOTE: add_limit adds a global limit, you can remove this later
# NOTE: you will need to select which endpoints to render, you 
# can just hit Enter and all will be rendered.
dlt-init-openapi fivetran --url https://raw.githubusercontent.com/dlt-hub/openapi-specs/main/open_api_specs/Business/fivetran.yaml --global-limit 2
cd fivetran_pipeline
# install generated requirements
pip install -r requirements.txt

The last command will install the required dependencies for your pipeline. The dependencies are listed in the requirements.txt:

dlt>=0.4.12

You now have the following folder structure in your project:

fivetran_pipeline/
├── .dlt/
│   ├── config.toml          # configs for your pipeline
│   └── secrets.toml         # secrets for your pipeline
├── rest_api/                # The rest api verified source
│   └── ...
├── fivetran/                
│   └── __init__.py          # TODO: possibly tweak this file
├── fivetran_pipeline.py        # your main pipeline script
├── requirements.txt         # dependencies for your pipeline
└── .gitignore               # ignore files for git (not required)

1.1. Tweak fivetran/__init__.py​

This file contains the generated configuration of your rest_api. You can continue with the next steps and leave it as is, but you might want to come back here and make adjustments if you need your rest_api source set up in a different way. The generated file for the fivetran source will look like this:

2. Configuring your source and destination credentials​

info

dlt-init-openapi will try to detect which authentication mechanism (if any) is used by the API in question and add a placeholder in your secrets.toml.

  • If you know your API needs authentication, but none was detected, you can learn more about adding authentication to the rest_api here.
  • OAuth detection currently is not supported, but you can supply your own authentication mechanism as outlined here.

The dlt cli will have created a .dlt directory in your project folder. This directory contains a config.toml file and a secrets.toml file that you can use to configure your pipeline. The automatically created version of these files look like this:

generated config.toml​


[runtime]
log_level="INFO"

[sources.fivetran]
# Base URL for the API
base_url = "https://api.fivetran.com"

generated secrets.toml​


[sources.fivetran]
# secrets for your fivetran source
username = "FILL ME OUT"  # TODO: fill in your credentials
password = "FILL ME OUT"  # TODO: fill in your credentials

2.1. Adjust the generated code to your usecase​

Further help setting up your source and destinations

At this time, the dlt-init-openapi cli tool will always create pipelines that load to a local duckdb instance. Switching to a different destination is trivial, all you need to do is change the destination parameter in fivetran_pipeline.py to postgres and supply the credentials as outlined in the destination doc linked below.

  • Read more about setting up the rest_api source in our docs.
  • Read more about setting up the CockroachDB destination in our docs.

3. Running your pipeline for the first time​

The dlt cli has also created a main pipeline script for you at fivetran_pipeline.py, as well as a folder fivetran that contains additional python files for your source. These files are your local copies which you can modify to fit your needs. In some cases you may find that you only need to do small changes to your pipelines or add some configurations, in other cases these files can serve as a working starting point for your code, but will need to be adjusted to do what you need them to do.

The main pipeline script will look something like this:


import dlt

from fivetran import fivetran_source


if __name__ == "__main__":
    pipeline = dlt.pipeline(
        pipeline_name="fivetran_pipeline",
        destination='duckdb',
        dataset_name="fivetran_data",
        progress="log",
        export_schema_path="schemas/export"
    )
    source = fivetran_source()
    info = pipeline.run(source)
    print(info)

Provided you have set up your credentials, you can run your pipeline like a regular python script with the following command:

python fivetran_pipeline.py

4. Inspecting your load result​

You can now inspect the state of your pipeline with the dlt cli:

dlt pipeline fivetran_pipeline info

You can also use streamlit to inspect the contents of your CockroachDB destination for this:

# install streamlit
pip install streamlit
# run the streamlit app for your pipeline with the dlt cli:
dlt pipeline fivetran_pipeline show

5. Next steps to get your pipeline running in production​

One of the beauties of dlt is, that we are just a plain Python library, so you can run your pipeline in any environment that supports Python >= 3.8. We have a couple of helpers and guides in our docs to get you there:

The Deploy section will show you how to deploy your pipeline to​

  • Deploy with GitHub Actions: Learn how to deploy your dlt pipeline using GitHub Actions for CI/CD. Follow the guide here.
  • Deploy with Airflow: Discover how to deploy your pipeline with Airflow and Google Composer. Detailed instructions can be found here.
  • Deploy with Google Cloud Functions: Find out how to deploy your dlt pipeline using Google Cloud Functions by following this guide here.
  • Other Deployment Methods: Explore additional deployment methods for your dlt pipeline here.

The running in production section will teach you about:​

  • How to Monitor your pipeline: Learn to monitor your dlt pipeline in production to ensure smooth operation and quickly identify any issues. Read more here.
  • Set up alerts: Set up alerts to get notified about important events and issues in your dlt pipeline. This helps in proactive issue resolution. Find out how here.
  • Set up tracing: Implement tracing in your dlt pipeline to track the flow and performance of your data processing steps. Detailed instructions are available here.
