Installation

dlt supports Python 3.8+.

pip install dlt

More options: Install via Conda or Pixi

Quick Start

Load chess game data from chess.com API and save it in DuckDB:

import dlt
from dlt.sources.helpers import requests

# Create a dlt pipeline that will load
# chess player data to the DuckDB destination
pipeline = dlt.pipeline(
    pipeline_name='chess_pipeline',
    destination='duckdb',
    dataset_name='player_data'
)

# Grab some player data from Chess.com API
data = []
for player in ['magnuscarlsen', 'rpragchess']:
    response = requests.get(f'https://api.chess.com/pub/player/{player}')
    response.raise_for_status()
    data.append(response.json())

# Extract, normalize, and load the data
pipeline.run(data, table_name='player')

Try it out in our Colab Demo

Adding as dependency

dlt follows the semantic versioning with the MAJOR.MINOR.PATCH pattern. Currently, we are using pre-release versioning with the major version being 0.

• minor version change means breaking changes
• patch version change means new features that should be backward compatible
• any suffix change, e.g., post10 -> post11, is considered a patch

We suggest that you allow only patch level updates automatically:

• Using the Compatible Release Specifier. For example dlt~=0.3.10 allows only versions >=0.3.10 and less than <0.4
• Poetry caret requirements. For example ^0.3.10 allows only versions >=0.3.10 to <0.4
