Python Data Loading from stripe to databricks using dlt Library

Need help deploying these pipelines, or figuring out how to run them in your data stack?

Join our Slack community or book a call with our support engineer Violetta.

This page provides technical documentation on how to load data from Stripe, a comprehensive payments platform that supports 135+ currencies, into Databricks, a unified data analytics platform. The process is facilitated using an open-source Python library called dlt. Stripe's simple APIs and transparent pricing make it an ideal choice for businesses looking to scale faster. Databricks, on the other hand, accelerates innovation by unifying data science, engineering, and business. The dlt library serves as a bridge, enabling efficient data transfer between these two platforms. For more information about Stripe, please visit https://stripe.com.

dlt Key Features​

  • Automated maintenance: With schema inference and evolution and alerts, and with short declarative code, maintenance becomes simple. You can read more about it here.
  • Run it where Python runs: dlt can run on Airflow, serverless functions, notebooks. No external APIs, backends or containers, scales on micro and large infra alike. You can read more about it here.
  • User-friendly, declarative interface: dlt removes knowledge obstacles for beginners while empowering senior professionals. You can read more about it here.
  • Getting started with dlt: Dive into the Getting started guide for a quick intro to the essentials of dlt.
  • Join the dlt community: Give the library a ⭐ and check out the code on GitHub. Ask questions and share how you use the library on Slack. You can read more about it here.

Getting started with your pipeline locally​

0. Prerequisites​

dlt requires Python 3.8 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​

First you need to install the dlt library with the correct extras for Databricks:

pip install "dlt[databricks]"

The dlt cli has a useful command to get you started with any combination of source and destination. For this example, we want to load data from Stripe to Databricks. You can run the following commands to create a starting point for loading data from Stripe to Databricks:

# create a new directory
mkdir stripe_analytics_pipeline
cd stripe_analytics_pipeline
# initialize a new pipeline with your source and destination
dlt init stripe_analytics databricks
# install the required dependencies
pip install -r requirements.txt

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


pandas>=2.0.0
stripe>=5.0.0
dlt[databricks]>=0.3.5

You now have the following folder structure in your project:

stripe_analytics_pipeline/
├── .dlt/
│   ├── config.toml          # configs for your pipeline
│   └── secrets.toml         # secrets for your pipeline
├── stripe_analytics/                   # folder with source specific files
│   └── ...
├── stripe_analytics_pipeline.py        # your main pipeline script
├── requirements.txt         # dependencies for your pipeline
└── .gitignore               # ignore files for git (not required)

2. Configuring your source and destination credentials​

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​

# put your configuration values here

[runtime]
log_level="WARNING"  # the system log level of dlt
# use the dlthub_telemetry setting to enable/disable anonymous usage data reporting, see https://dlthub.com/docs/telemetry
dlthub_telemetry = true

generated secrets.toml​

# put your secret values and credentials here. do not share this file and do not push it to github

[sources.stripe_analytics]
stripe_secret_key = "stripe_secret_key" # please set me up!

[destination.databricks.credentials]
catalog = "catalog" # please set me up!
server_hostname = "server_hostname" # please set me up!
http_path = "http_path" # please set me up!
access_token = "access_token" # please set me up!

2.1. Adjust the generated code to your usecase​

Further help setting up your source and destinations
  • Read more about setting up the Stripe source in our docs.
  • Read more about setting up the Databricks 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 stripe_analytics_pipeline.py, as well as a folder stripe_analytics 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:


from typing import Optional, Tuple

import dlt
from pendulum import DateTime, datetime
from stripe_analytics import (
    ENDPOINTS,
    INCREMENTAL_ENDPOINTS,
    incremental_stripe_source,
    metrics_resource,
    stripe_source,
)


def load_data(
    endpoints: Tuple[str, ...] = ENDPOINTS + INCREMENTAL_ENDPOINTS,
    start_date: Optional[DateTime] = None,
    end_date: Optional[DateTime] = None,
) -> None:
    """
    This demo script uses the resources with non-incremental
    loading based on "replace" mode to load all data from provided endpoints.

    Args:

        start_date: An optional start date to limit the data retrieved. Defaults to None.
        end_date: An optional end date to limit the data retrieved. Defaults to None.

    pipeline = dlt.pipeline(
        pipeline_name="stripe_analytics",

    print(load_info)

    )
    # load Subscription and Event data, calculate metrics, store them in a database
    load_data_and_get_metrics()

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

python stripe_analytics_pipeline.py

4. Inspecting your load result​

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

dlt pipeline stripe_analytics info

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

# install streamlit
pip install streamlit
# run the streamlit app for your pipeline with the dlt cli:
dlt pipeline stripe_analytics 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: dlt allows you to deploy your pipeline using Github Actions. This is a CI/CD runner that can be used basically for free. You can find detailed instructions on how to do this here.
  • Deploy with Airflow: Another way to deploy your dlt pipeline is by using Airflow. dlt provides a wrapper to make this process trivial. Learn more about deploying with Airflow here.
  • Deploy with Google Cloud Functions: You can also deploy your dlt pipeline using Google Cloud Functions. This allows you to execute your pipeline in response to an event, without having to manage a server. Find out how to deploy with Google Cloud Functions here.
  • Other deployment methods: dlt supports a variety of other deployment methods to meet your specific needs. You can explore these other methods here.

The running in production section will teach you about:​

  • Monitor Your Pipeline: With dlt, you can easily monitor your data loading pipeline. This allows you to track the progress of your pipeline and identify any issues that may arise during the data loading process. More details can be found here.
  • Set Up Alerts: dlt provides a feature to set up alerts. This is particularly useful to get notified about any failures or issues in your pipeline. This helps in ensuring that your data pipeline runs smoothly without any interruptions. Learn more about it here.
  • Set Up Tracing: Tracing in dlt allows you to track the flow of your data from the source to the destination. This is useful for debugging and understanding the performance of your pipeline. Find out more here.
