What is Delta Sharing?

Delta Sharing is an open-source protocol developed by Databricks that enables secure and real-time data sharing across different organizations, platforms, and cloud environments without replication. This innovative technology allows you to share live data from Delta Lake tables stored in Databricks, AWS, Azure, or any cloud storage with external clients without moving or copying data. Clients can access shared data using Python, SQL, Apache Spark, or BI tools like Power BI and Tableau.

Key Features of Delta Sharing

Cross-Platform Data Sharing

Delta Sharing enables you to share data between different cloud providers, such as AWS, GCP, Azure, and even on-prem systems. This feature allows for seamless data sharing across various platforms, making it an ideal solution for organizations with multi-cloud or hybrid environments.

No Data Duplication

Unlike traditional file-based sharing (CSV, Parquet), data is not copied. Consumers query live data directly, reducing the risk of data duplication and ensuring that only the most up-to-date information is shared.

Secure and Controlled Access

Delta Sharing supports access control with tokens and policies, ensuring that only authorized users can see the data. This feature provides an additional layer of security, making it an ideal solution for organizations with sensitive data.

Supports Multiple Clients

Delta Sharing works with BigQuery, Spark, Python, Pandas, SQL, Power BI, and Tableau, making it a versatile solution for various data analysis and visualization tools.

Efficient Data Delivery

Delta Sharing uses Parquet and Delta Lake formats, enabling fast and efficient data access. This feature ensures that data is delivered quickly and efficiently, reducing the risk of data latency and improving overall data sharing performance.

How Delta Sharing Works

Data Provider (Owner)

The data provider defines tables in Delta Lake and shares data via the Delta Sharing Server. The data provider grants access using tokens, ensuring that only authorized users can access the shared data.

Data Consumer

The data consumer uses the Delta Sharing client (Python, SQL, BI tool) to retrieve data via a secure REST API. The data consumer can read real-time data without duplication, ensuring that they have access to the most up-to-date information.

Comparison: Delta Sharing vs Traditional Data Sharing

Feature	Delta Sharing	CSV/Parquet Files	API-based Sharing
Data Movement	No	Yes	Yes
Live Updates	Yes	No	Limited
Cross-Cloud Sharing	Yes	No	Limited
Access Control	Yes	No	Yes
Performance	High (Parquet/Delta format)	Medium	High

As the comparison table shows, Delta Sharing offers several advantages over traditional data sharing methods, including no data duplication, live updates, and cross-cloud sharing.

Use Cases

Delta Sharing is ideal for various use cases, including:

Sharing financial transaction data with external partners
Providing real-time analytics data to vendors or business units
Cross-company collaboration without complex ETL pipelines
Regulated data sharing where access must be controlled but not duplicated

Conclusion

Delta Sharing is a powerful way to share live data securely and efficiently without duplication. It allows BigQuery, Spark, and other clients to directly access shared data using the Delta Sharing protocol. By leveraging Delta Sharing, organizations can unlock efficient and secure data sharing, improving collaboration and reducing the risk of data duplication.
