🔀 ADF vs Databricks for Orchestration

🏁 Pit Stop Summary "The best fuel in the world is useless if it never reaches the car." Your fuel tank (ADLS Gen2) is ready and waiting. But raw data doesn't teleport itself from SAP, Salesforce, IoT devices, or REST APIs into your lake. You need a logistics system — and that's Azure Data Factory (ADF). ADF is the fuel truck fleet of your data platform. It moves data. It doesn't transform it deeply (that's Spark's job), but it knows every road, every connection type, and every schedule. Think of ADF as the logistics manager, not the engineer. It coordinates movement. Databricks does the heavy manufacturing. A Linked Service is a connection definition — it tells ADF how to connect to a system. Each source or destination system needs one. A Dataset describes the shape and location of data at a linked service. It's the cargo manifest for your fuel truck. A Pipeline is a sequence of activities — Copy, Execute Notebook, Delete, Validation, and more. It's the delivery route the truck follows. Triggers define when a pipeline runs: Load everything from source each time. Simple, but expensive at scale. Only load rows newer than the last run. Use a watermark column (e.g., updated_at). An event trigger fires when a file lands in a watched container. Ideal for partner data feeds, SFTP drops, and IoT batches. A common question: should I orchestrate with ADF or with Databricks Workflows? In practice, many platforms use both: ADF for ingestion orchestration, Databricks Workflows for transformation orchestration. Next Episode → The fuel is in the tank. Now let's meet the race car — Azure Databricks itself. Templates let you quickly answer FAQs or store snippets for re-use. Are you sure you want to ?
