An adapter for MLflow to use CrateDB as a storage database for MLflow Tracking. MLflow is an open source platform to manage the whole ML lifecycle, including experimentation, reproducibility, deployment, and a central model registry.


Install the most recent version of the mlflow-cratedb package.

pip install --upgrade 'mlflow-cratedb[examples]'

To verify if the installation worked, you can inspect the version numbers of the software components you just installed.

mlflow-cratedb --version
mlflow-cratedb cratedb --version


The MLflow Tracking subsystem is about recording and querying experiments, across code, data, config, and results.

The MLflow adapter for CrateDB can be used in different ways. Please refer to the handbook, and the documentation about container usage.

For more general information, see Machine Learning with CrateDB and examples about MLflow and CrateDB.
