SQL Databases using the Apache Spark connector

The Apache Spark connector for Azure SQL Database and SQL Server enables these databases to act as input data sources and output data sinks for Apache Spark jobs. It allows you to use real-time transactional data in big data analytics and persist results for ad-hoc queries or reporting.

Compared to the built-in JDBC connector, this connector provides the ability to bulk insert data into SQL databases. It can outperform row-by-row insertion with 10x to 20x faster performance. The Spark connector for SQL Server and Azure SQL Database also supports Azure Active Directory (Azure AD) authentication, enabling you to connect securely to your Azure SQL databases from Azure Databricks using your Azure AD account. It provides interfaces that are similar to the built-in JDBC connector. It is easy to migrate your existing Spark jobs to use this connector.


There are two versions of the Spark connector for SQL Server: one for Spark 2.4 and one for Spark 3.0. The Spark 3.0 connector is available in preview and works with Databricks Runtime 7.x and above. The connector is community-supported and does not include Microsoft SLA support. File any issues on GitHub to engage the community for help.
