Li Yu, et al, explain how to use Databricks notebooks and MLflow to automate deployment and testing of Spark solutions:

Today many data science (DS) organizations are accelerating the agile analytics development process using Databricks notebooks.  Fully leveraging the distributed computing power of Apache Spark™, these organizations are able to interact easily with data at multi-terabytes scale, from exploration to fast prototype and all the way to productionize sophisticated machine learning (ML) models.  As fast iteration is achieved at high velocity, what has become increasingly evident is that it is non-trivial to manage the DS life cycle for efficiency, reproducibility, and high-quality. The challenge multiplies in large enterprises where data volume grows exponentially, the expectation of ROI is high on getting business value from data, and cross-functional collaborations are common.

In this blog, we introduce a joint work with Iterable that hardens the DS process with best practices from software development.  This approach automates building, testing, and deployment of DS workflow from inside Databricks notebooks and integrates fully with MLflow and Databricks CLI. It enables proper version control and comprehensive logging of important metrics, including functional and integration tests, model performance metrics, and data lineage. All of these are achieved without the need to maintain a separate build server.
