Deployment configuration file reference for big data clusters
Applies to: 
SQL Server 2019 (15.x)
Important
The Microsoft SQL Server 2019 Big Data Clusters add-on will be retired. Support for SQL Server 2019 Big Data Clusters will end on February 28, 2025. All existing users of SQL Server 2019 with Software Assurance will be fully supported on the platform and the software will continue to be maintained through SQL Server cumulative updates until that time. For more information, see the announcement blog post and Big data options on the Microsoft SQL Server platform.
This article provides a JSON file that documents the structure of a SQL Server 2019 big data cluster deployment configuration file.
Tip
Do not use this as your actual deployment configuration file. Instead, follow the instructions in the deployment guidance for how to work with configuration files.
Warning
The parameter imagePullPolicy is required to be set as "Always" in the deployment profile control.json file.
Deployment configuration file
Use the following JSON file as a reference for the structure and settings in a big data cluster deployment configuration file.
