How to Get Started with Databricks

Databricks generally offers a 14-day free trial that you can use on your preferred cloud platform like Google Cloud, AWS, or Azure. Follow these steps to set up Databricks on Google Cloud Platform.

Step 1: Search for Databricks

• Open the Google Cloud Platform.
• Go to the Marketplace.
• Search for "Databricks."
• Sign up for the free trial.

Step 2: Start the Trial Subscription

• Once you start the trial, you will get a link from the Databricks menu item in Google Cloud Platform.
• Use this link to manage the setup on the Databricks account management page.

Step 3: Create a Workspace

• After setting up the trial, you need to create a Workspace in Databricks.
• The Workspace is where you access your data and tools.
• To do this, you will need to use the external Databricks web application (Control Plane).

Step 4: Set Up a Kubernetes Cluster

• To create a Workspace, you need to set up a three-node Kubernetes cluster in your Google Cloud Platform project using Google Kubernetes Engine (GKE).
• This cluster will host the Databricks Runtime, which is called the Data Plane.
• It's important to know that your data always stays in your cloud account and in your own data sources (Data Plane), not in the Control Plane. This way, you keep control and ownership of your data.

Step 5: Create a Table in Delta Lake

• To create a table in Delta Lake, you can upload a file, connect to supported data sources, or use a partner integration.

Step 6: Create a Cluster to Analyze Your Data

• To analyze your data, you need to create a "Cluster."
• A Databricks Cluster is a combination of computation resources and settings where you can run jobs and notebooks.
• You can use a Databricks Cluster for tasks like streaming analytics, ETL pipelines, machine learning, and ad-hoc analytics.

Step 7: Understand the Databricks Runtime

• The runtime of the cluster in Databricks is based on Apache Spark.
• Most of the tools in Databricks use open-source technologies and libraries like Delta Lake and MLflow.
