Load Data from GitLab
to YugabyteDB
Using dlt
in Python
We will be using the dlt PostgreSQL destination to connect to YugabyteDB. You can get the connection string for your YugabyteDB database as described in the YugabyteDB Docs.

Loading data from GitLab
to YugabyteDB
can streamline your DevOps processes by combining the robust features of both platforms. GitLab
is a web-based DevOps lifecycle tool that offers a Git repository manager, wiki, issue-tracking, and CI/CD pipeline features under an open-source license. YugabyteDB
is a distributed PostgreSQL database designed for modern applications, providing built-in resilience, seamless scalability, and flexible geo-distribution with PostgreSQL-compatible and Cassandra-inspired APIs. Using the open-source Python library dlt
, you can efficiently extract data from GitLab
and load it into YugabyteDB
. This documentation will guide you through the process, leveraging dlt
to ensure data consistency and integrity. For more details about GitLab
, visit here.

Key Features
- Pipeline Metadata:
dlt
pipelines leverage metadata to provide governance capabilities, including load IDs for incremental transformations and data lineage. Read more. - Schema Enforcement and Curation:
dlt
empowers users to enforce and curate schemas, ensuring data consistency and quality. Read more. - Scalability via Iterators, Chunking, and Parallelization:
dlt
offers scalable data extraction by leveraging iterators, chunking, and parallelization techniques. Read more. - Implicit Extraction DAGs:
dlt
incorporates the concept of implicit extraction DAGs to handle dependencies between data sources and their transformations automatically. Read more. - Automated Maintenance: With schema inference and evolution and alerts,
dlt

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 gitlab --url https://raw.githubusercontent.com/dlt-hub/openapi-specs/main/open_api_specs/Public/gitlab.yaml --global-limit 2
cd gitlab_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:
gitlab_pipeline/
├── .dlt/
│ ├── config.toml # configs for your pipeline
│ └── secrets.toml # secrets for your pipeline
├── rest_api/ # The rest api verified source
│ └── ...
├── gitlab/
│ └── __init__.py # TODO: possibly tweak this file
├── gitlab_pipeline.py # your main pipeline script
├── requirements.txt # dependencies for your pipeline
└── .gitignore # ignore files for git (not required)
1.1. Tweak gitlab/__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 gitlab source will look like this:

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.gitlab]
# Base URL for the API
base_url = "https://www.gitlab.com/api/v4"
generated secrets.toml
[sources.gitlab]
# secrets for your gitlab source
api_key = "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 gitlab_pipeline.py
to postgres and supply the credentials as outlined in the destination doc linked below.
3. Running your pipeline for the first time
The dlt
cli has also created a main pipeline script for you at gitlab_pipeline.py
, as well as a folder gitlab
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 gitlab import gitlab_source
if __name__ == "__main__":
pipeline = dlt.pipeline(
pipeline_name="gitlab_pipeline",
destination='duckdb',
dataset_name="gitlab_data",
progress="log",
export_schema_path="schemas/export"
)
source = gitlab_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 gitlab_pipeline.py
4. Inspecting your load result
You can now inspect the state of your pipeline with the dlt
cli:
dlt pipeline gitlab_pipeline info
You can also use streamlit to inspect the contents of your YugabyteDB
destination for this:
# install streamlit
pip install streamlit
# run the streamlit app for your pipeline with the dlt cli:
dlt pipeline gitlab_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 pipeline using GitHub Actions for CI/CD. Read more
- Deploy with Airflow and Google Composer: Follow this guide to deploy your pipeline with Airflow, including a managed environment with Google Composer. Read more
- Deploy with Google Cloud Functions: Explore how to deploy your pipeline using Google Cloud Functions for serverless execution. Read more
- Other Deployment Options: Discover various other methods to deploy your pipeline, including detailed guides and walkthroughs. Read more
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 identification of issues. Read more here. - Set up alerts: Setting up alerts can help you stay informed about your pipeline's performance and any potential issues that may arise. Find out how here.
- Set up tracing: Tracing allows you to track the execution of your pipeline, providing valuable insights into its behavior and performance. Learn how to set up tracing here.
