Getting Started with Delta Sharing in Azure Databricks

 Delta Sharing is a feature in Azure Databricks that enables you to share data from your Delta Lake with external organizations. It provides a simple and secure way to share data without the need to copy or move it, ensuring that recipients always have access to the most up-to-date information.

Step 1: Enable Delta Sharing.
Before you can create shares, you need to enable Delta Sharing in your Databricks workspace. This is typically done by a workspace administrator.
sql
-- Enable Delta Sharing
SET spark.databricks.delta.sharing.enabled = true;

Step 2: Create a Share.
A share is a container that holds one or more shared tables. You can create a share using the CREATE SHARE command.
sql
-- Create a share named 'sales_share'
CREATE SHARE sales_share;

Step 3: Add Tables to the Share.
Once you have a share, you can add Delta tables to it. These tables are what you'll be sharing with external recipients.
sql
-- Add a table to the share
ALTER SHARE sales_share ADD TABLE sales_data;

Step 4: Create a Recipient.
A recipient is an external entity with whom you want to share data. You can create a recipient using the CREATE RECIPIENT command.
sql
-- Create a recipient named 'partner_company'
CREATE RECIPIENT partner_company;

Step 5: Grant Permissions.
After creating a recipient, you need to grant them permission to access the share. This is done using the GRANT command.
sql
-- Grant SELECT permission to the recipient
GRANT SELECT ON SHARE sales_share TO RECIPIENT partner_company;

Step 6: Share the Endpoint Once you have set up the share and granted permissions, you can share the endpoint URL with the recipient. They can use this URL to access the shared data using Delta Sharing clients.

Conclusion: Delta Sharing in Azure Databricks provides a powerful and secure way to share data across organizations. By following the steps outlined in this post, you can easily set up a share, add tables to it, create recipients, and grant them access to your data.
