with dlt
in Python
Join our Slack community or book a call with our support engineer Violetta.
Aladtec
is a robust scheduling and workforce management system designed for public safety and healthcare organizations. It helps streamline employee scheduling, manage shift trades, and track work hours efficiently. With Aladtec
, organizations can optimize staffing, reduce scheduling conflicts, and ensure compliance with labor laws. The platform offers features like automated scheduling, time-off requests, and detailed reporting to enhance productivity and operational efficiency.
This documentation provides guidance on loading data from Aladtec
to Azure Cloud Storage
using the open-source python library dlt
. Azure Cloud Storage
stores data on Microsoft Azure, enabling the creation of data lakes. You can upload data as JSONL, Parquet, or CSV. Further information about the source is available at Aladtec.

- Pipeline Metadata:
dlt
pipelines leverage metadata to provide governance capabilities, including load IDs for incremental transformations and data lineage. Learn more - Schema Enforcement and Curation: Ensure data consistency and quality by enforcing and curating schemas. Learn more
- Schema Evolution: Proactively manage schema changes with alerts and notifications, helping maintain data integrity. Learn more
- Scaling and Finetuning: Scale up and fine-tune pipelines with parallel processing, thread pools, and memory buffer adjustments. Learn more
- Scalability via Iterators and Parallelization: Efficiently process large datasets by leveraging iterators, chunking, and parallelization techniques. Learn more
Getting started with your pipeline locally
dlt-init-openapi
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 aladtec --url https://raw.githubusercontent.com/dlt-hub/openapi-specs/main/open_api_specs/Business/aladtec.yaml --global-limit 2
cd aladtec_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:
aladtec_pipeline/
├── .dlt/
│ ├── config.toml # configs for your pipeline
│ └── secrets.toml # secrets for your pipeline
├── rest_api/ # The rest api verified source
│ └── ...
├── aladtec/
│ └── __init__.py # TODO: possibly tweak this file
├── aladtec_pipeline.py # your main pipeline script
├── requirements.txt # dependencies for your pipeline
└── .gitignore # ignore files for git (not required)
1.1. Tweak aladtec/__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 aladtec source will look like this:

return rest_api_source(source_config)
2. Configuring your source and destination credentials
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
.
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.aladtec]
# Base URL for the API
base_url = "https://..." # Replace with API base URL
generated secrets.toml
[sources.aladtec]
# secrets for your aladtec source
token = "FILL ME OUT" # TODO: fill in your credentials
2.1. Adjust the generated code to your usecase
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 aladtec_pipeline.py
to filesystem and supply the credentials as outlined in the destination doc linked below.
The default filesystem destination is configured to connect to AWS S3. To load to Azure Cloud Storage, update the [destination.filesystem.credentials]
section in your secrets.toml
.
[destination.filesystem.credentials]
azure_storage_account_name="Please set me up!"
azure_storage_account_key="Please set me up!"
By default, the filesystem destination will store your files as JSONL
. You can tell your pipeline to choose a different format with the loader_file_format
property that you can set directly on the pipeline or via your config.toml
. Available values are jsonl
, parquet
and csv
:
[pipeline] # in ./dlt/config.toml
loader_file_format="parquet"
3. Running your pipeline for the first time
The dlt
cli has also created a main pipeline script for you at aladtec_pipeline.py
, as well as a folder aladtec
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 aladtec import aladtec_source
if __name__ == "__main__":
pipeline = dlt.pipeline(
pipeline_name="aladtec_pipeline",
destination='duckdb',
dataset_name="aladtec_data",
progress="log",
export_schema_path="schemas/export"
)
source = aladtec_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 aladtec_pipeline.py
4. Inspecting your load result
You can now inspect the state of your pipeline with the dlt
cli:
dlt pipeline aladtec_pipeline info
You can also use streamlit to inspect the contents of your Azure Cloud Storage
destination for this:
# install streamlit
pip install streamlit
# run the streamlit app for your pipeline with the dlt cli:
dlt pipeline aladtec_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: Use GitHub Actions to automate your deployment process. Follow the guide here.
- Deploy with Airflow and Google Composer: Leverage Airflow and Google Composer for managing your dlt deployments. Learn more here.
- Deploy with Google Cloud Functions: Utilize Google Cloud Functions for serverless deployment of your dlt pipelines. Detailed instructions can be found here.
- Explore Other Deployment Options: Discover various other methods to deploy your dlt pipelines by visiting this comprehensive guide here.
The running in production section will teach you about:
- How to Monitor your pipeline: Learn how to effectively monitor your
dlt
pipeline in production to ensure smooth operation and quick issue resolution. How to Monitor your pipeline - Set up alerts: Set up alerts to get notified about important events or issues in your
dlt
pipeline, allowing for proactive management. Set up alerts - And set up tracing: Implement tracing to get detailed insights into the execution of your
dlt
pipeline, including timing and configuration information. And set up tracing
