mlflow.autolog() integrates with popular ML libraries to automatically log hyperparameters, metrics, and artifacts—enabling efficient tracking and comparison of tuning experiments with no manual effort.

Leverage the native integration between MLflow and Optuna to run distributed hyperparameter optimization at scale using Spark UDFs. The MLflow tracking server provides robust trial data storage that persists through node failures, ensuring your optimization jobs complete successfully even in complex scalable distributed environments.

By visualizing metrics across runs directly in the MLflow UI, users can quickly evaluate tradeoffs and identify the best model for production.
