Load Data from Attio to Microsoft SQL Server with dlt in Python

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.

Loading data from Attio to Microsoft SQL Server with the open-source Python library dlt enables teams to manage their relationships, track deals, and organize work efficiently. Attio is a collaborative workspace designed to streamline team operations, while Microsoft SQL Server is a robust relational database management system (RDBMS) that supports a variety of applications and tools. By leveraging dlt, users can seamlessly transfer data from Attio to Microsoft SQL Server, ensuring data integrity and consistency. For more information about Attio, visit here.

dlt Key Features

• Easy to get started: dlt is a Python library that is easy to use and understand. It is designed to be simple to use and easy to understand. Type pip install dlt and you are ready to go.
• Automated Data Normalization: The configurable normalization engine in dlt recursively unpacks nested structures into relational tables. Learn more.
• Idempotent and Atomic Loads: dlt ensures data safely ends up in your chosen destination with idempotent and atomic loads. Learn more.
• Schema Evolution: dlt automatically evolves schemas to accommodate future source data changes. Learn more.
• Supports Multiple Destinations: dlt can load data to various destinations like Google BigQuery, Microsoft SQL Server, and DuckDB. 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 attio --url https://raw.githubusercontent.com/dlt-hub/openapi-specs/main/open_api_specs/Business/attio_api.yaml --global-limit 2
cd attio_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:

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

1.1. Tweak attio/__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 attio 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.attio]
# Base URL for the API
# Production
base_url = "https://api.attio.com"

generated secrets.toml

[sources.attio]
# secrets for your attio source
# example_api_key = "example value"

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 attio_pipeline.py to mssql 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 Microsoft SQL Server 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 attio_pipeline.py, as well as a folder attio 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 attio import attio_source


if __name__ == "__main__":
    pipeline = dlt.pipeline(
        pipeline_name="attio_pipeline",
        destination='duckdb',
        dataset_name="attio_data",
        progress="log",
        export_schema_path="schemas/export"
    )
    source = attio_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 attio_pipeline.py

4. Inspecting your load result

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

dlt pipeline attio_pipeline info

You can also use streamlit to inspect the contents of your Microsoft SQL Server destination for this:

# install streamlit
pip install streamlit
# run the streamlit app for your pipeline with the dlt cli:
dlt pipeline attio_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 use GitHub Actions for CI/CD to deploy your dlt pipeline. Follow the guide here.
• Deploy with Airflow: Use Google Composer, a managed Airflow environment, to deploy your dlt pipeline. Detailed instructions can be found here.
• Deploy with Google Cloud Functions: Discover how to deploy your dlt pipeline using Google Cloud Functions. Check out the guide here.
• Explore other deployment options: There are various other methods to deploy your dlt pipeline. Find more options and guides here.

The running in production section will teach you about:

• How to Monitor your pipeline: Learn how to effectively monitor your dlt pipeline to ensure smooth and efficient operation. Read more
• Set up alerts: Setting up alerts helps you stay informed about the status of your pipeline, enabling you to respond quickly to any issues. Read more
• Set up tracing: Implement tracing to get detailed insights into the execution of your pipeline, including timing information and configuration details. Read more
