Building Databricks workflows

Databricks workflows are a way to automate and orchestrate your data processing tasks on the Databricks platform. You can use workflows to create pipelines, ETL processes, machine learning models, and more.

A workflow can be defined using the Databricks UI, the Databricks CLI, or the Databricks REST API. A workflow can also have parameters that can be passed to it at runtime. A workflow can have one or more runs, which are the instances of the workflow execution.
