An AutoML pipeline for time series runs on Ray backend with a real-spark integration to launch distributed trials, use Ray Tune for hyperparameter search, and write best pipelines to HDFS for later inference. It automates feature generation, model selection (RNNs, attention, boosting), and tuning; users forecast a week of history to predict two hours ahead for hundreds of thousands of cells — scale can reach two million series. Customers report faster deployment and improved accuracy, but missing-value quality problems still break some cases.
