Databricks is a data analytics platform that lets you easily integrate with open source libraries. It offers a simple collaborative environment to run interactive and scheduled data analysis workloads.

RudderStack supports Databricks as a source from which you can ingest data and route it to your desired downstream destinations.

Granting permissions

RudderStack requires you to grant certain user permissions on Databricks to successfully access data from it.

Follow the steps listed in the following sections in the exact order to grant these permissions:

Step 1: Add a user

• Add a new user (for example, user@example.com) by following the steps in the Databricks documentation.

Step 2: Creating the RudderStack schema and granting permissions

1. Create a dedicated schema _rudderstack.

Copy
CREATE SCHEMA `_rudderstack`;

2. Grant full access to the schema _rudderstack for the user created in step 1.

Copy
GRANT ALL PRIVILEGES ON SCHEMA `_rudderstack` TO `user@example.com`

Replace user@example.com with the user created in step 1.
