Run apps with azdata - SQL Server Big Data Clusters

  • आलेख

This article describes how to run an application inside a SQL Server Big Data Clusters.

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.

Prerequisites

Capabilities

In SQL Server 2019 you can create, delete, describe, initialize, list run and update your application. The following table describes the application deployment commands that you can use with azdata.

Command Description
azdata app describe Describe application.
azdata app run Run application.

The following sections describe these commands in more detail.

Run an app

If the app is in a Ready state, you can use it by running it with your specified input parameters. Use the following syntax to run an app:

azdata app run --name <app_name> --version <app_version> --inputs <inputs_params>

The following example command demonstrates the run command:

azdata app run --name add-app --version v1 --inputs x=1,y=2

If the run was successful, you should see your output as specified when you created the app. The following output is an example.

{
  "changedFiles": [],
  "consoleOutput": "",
  "errorMessage": "",
  "outputFiles": {},
  "outputParameters": {
    "result": 3
  },
  "success": true
}

Describe an app

The describe command provides detailed information about the app including the endpoint in your cluster. This is typically used by an app developer to build an app using the swagger client and using the webservice to interact with the app in a RESTful manner. For more information, see Consume applications on big data clusters for more information.
