Load Cloud Foundry UAA data in Python using dltHub

Build a Cloud Foundry UAA-to-database or-dataframe pipeline in Python using dlt with automatic Cursor support.

In this guide, we'll set up a complete Cloud Foundry UAA data pipeline from API credentials to your first data load in just 10 minutes. You'll end up with a fully declarative Python pipeline based on dlt's REST API connector, like in the partial example code below:

Example code
@dlt.source
def cloud_foundry_uaa_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "http://localhost/oauth/token/list/client",
            "auth": {
                "type": "bearer",
                "token": access_token,
            }
        },
        "resources": [
            "fzqsB1", "w12CnC"
        ],
    }
    [...]
    yield from rest_api_resources(config)


def get_data() -> None:
    # Connect to destination
    pipeline = dlt.pipeline(
        pipeline_name='cloud_foundry_uaa_pipeline',
        destination='duckdb',
        dataset_name='cloud_foundry_uaa_data', 
    )
    # Load the data
    load_info = pipeline.run(cloud_foundry_uaa_source())
    print(load_info)

Why use dltHub Workspace with LLM Context to generate Python pipelines?

  • Accelerate pipeline development with AI-native context
  • Debug pipelines, validate schemas and data with the integrated Pipeline Dashboard
  • Build Python notebooks for end users of your data
  • Low maintenance thanks to Schema evolution with type inference, resilience and self documenting REST API connectors. A shallow learning curve makes the pipeline easy to extend by any team member
  • dlt is the tool of choice for Pythonic Iceberg Lakehouses, bringing mature data loading to pythonic Iceberg with or without catalogs

What you’ll do

We’ll show you how to generate a readable and easily maintainable Python script that fetches data from cloud_foundry_uaa’s API and loads it into Iceberg, DataFrames, files, or a database of your choice. Here are some of the endpoints you can load:

  • Identity Providers: Endpoints related to managing identity providers, including configurations and raw settings.
  • Groups: Endpoints for managing external group mappings and related data.
  • OAuth Tokens: Endpoints for token management, including revocation and introspection.
  • Users: Endpoints for user management, including user status and specific user details.
  • MFA Providers: Endpoints for managing multi-factor authentication providers.
  • SAML Service Providers: Endpoints for handling SAML service provider configurations.
  • Logout: Endpoint for logging out users and redirecting them to a specified URL.

You will then debug the Cloud Foundry UAA pipeline using our Pipeline Dashboard tool to ensure it is copying the data correctly, before building a Notebook to explore your data and build reports.

Setup & steps to follow

💡
Before getting started, let's make sure Cursor is set up correctly:

Now you're ready to get started!

  1. ⚙️ Set up dlt Workspace

    Install dlt with duckdb support:

    pip install "dlt[workspace]"

    Initialize a dlt pipeline with Cloud Foundry UAA support.

    dlt init dlthub:cloud_foundry_uaa duckdb

    The init command will setup the necessary files and folders for the next step.

  2. 🤠 Start LLM-assisted coding

    Here’s a prompt to get you started:

    Prompt
    Please generate a REST API Source for Cloud Foundry UAA API, as specified in @cloud_foundry_uaa-docs.yaml 
Start with endpoints fzqsB1 and w12CnC and skip incremental loading for now. 
Place the code in cloud_foundry_uaa_pipeline.py and name the pipeline cloud_foundry_uaa_pipeline. 
If the file exists, use it as a starting point. 
Do not add or modify any other files. 
Use @dlt rest api as a tutorial. 
After adding the endpoints, allow the user to run the pipeline with python cloud_foundry_uaa_pipeline.py and await further instructions.

  3. 🔒 Set up credentials

    The snippets mention the "Authorization Code Grant" and "Client Credentials Grant" flows, but no specific details regarding keys, tokens, client IDs, client secrets, headers, header locations, token URLs, or refresh tokens are provided.

    To get the appropriate API keys, please visit the original source at https://docs.cloudfoundry.org/api/uaa/version/4.23.0/index.html. If you want to protect your environment secrets in a production environment, look into setting up credentials with dlt.

  4. 🏃‍♀️ Run the pipeline in the Python terminal in Cursor

    python cloud_foundry_uaa_pipeline.py

    If your pipeline runs correctly, you’ll see something like the following:

    Pipeline cloud_foundry_uaa load step completed in 0.26 seconds
1 load package(s) were loaded to destination duckdb and into dataset cloud_foundry_uaa_data
The duckdb destination used duckdb:/cloud_foundry_uaa.duckdb location to store data
Load package 1749667187.541553 is LOADED and contains no failed jobs

  5. 📈 Debug your pipeline and data with the Pipeline Dashboard

    Now that you have a running pipeline, you need to make sure it’s correct, so you do not introduce silent failures like misconfigured pagination or incremental loading errors. By launching the dlt Workspace Pipeline Dashboard, you can see various information about the pipeline to enable you to test it. Here you can see:

    • Pipeline overview: State, load metrics
    • Data’s schema: tables, columns, types, hints
    • You can query the data itself
    dlt pipeline cloud_foundry_uaa_pipeline show dashboard

  6. 🐍 Build a Notebook with data explorations and reports

    With the pipeline and data partially validated, you can continue with custom data explorations and reports. To get started, paste the snippet below into a new marimo Notebook and ask your LLM to go from there. Jupyter Notebooks and regular Python scripts are supported as well.

    import dlt

data = dlt.pipeline("cloud_foundry_uaa_pipeline").dataset()
# get "fzqsB1" table as Pandas frame
data."fzqsB1".df().head()
