Automate the library management process through Azure PowerShell cmdlets and REST APIs

You may want to manage your libraries for your serverless Apache Spark pools without going into the Synapse Analytics UI pages. For example, you may find that:

you develop a custom package and want to upload it to your workspace and use it in your Spark pool. And you want to finish the steps on your local tools without visiting the package management UIs.

In this article, we'll provide a general guide to help you managing libraries through Azure PowerShell cmdlets or REST APIs.

Manage packages through Azure PowerShell cmdlets

Add new libraries

  1. New-AzSynapseWorkspacePackage command can be used to upload new libraries to workspace.

    New-AzSynapseWorkspacePackage -WorkspaceName ContosoWorkspace -Package ".\ContosoPackage.whl"
    
  2. The combination of New-AzSynapseWorkspacePackage and Update-AzSynapseSparkPool commands can be used to upload new libraries to workspace and attach the library to a Spark pool.

    $package = New-AzSynapseWorkspacePackage -WorkspaceName ContosoWorkspace -Package ".\ContosoPackage.whl"
    Update-AzSynapseSparkPool -WorkspaceName ContosoWorkspace -Name ContosoSparkPool -PackageAction Add -Package $package
    
  3. If you want to attach an existing workspace library to your Spark pool, please refer to the command combination of Get-AzSynapseWorkspacePackage and Update-AzSynapseSparkPool.

    $packages = Get-AzSynapseWorkspacePackage -WorkspaceName ContosoWorkspace
    Update-AzSynapseSparkPool -WorkspaceName ContosoWorkspace -Name ContosoSparkPool -PackageAction Add -Package $packages
    

Remove libraries

  1. In order to remove a installed package from your Spark pool, please refer to the command combination of Get-AzSynapseWorkspacePackage and Update-AzSynapseSparkPool.

    $package = Get-AzSynapseWorkspacePackage -WorkspaceName ContosoWorkspace -Name ContosoPackage
    Update-AzSynapseSparkPool -WorkspaceName ContosoWorkspace -Name ContosoSparkPool -PackageAction Remove -Package $package
    
  2. You can also retrieve a Spark pool and remove all attached workspace libraries from the pool by calling Get-AzSynapseSparkPool and Update-AzSynapseSparkPool commands.

    $pool = Get-AzSynapseSparkPool -ResourceGroupName ContosoResourceGroup -WorkspaceName ContosoWorkspace -Name ContosoSparkPool
    $pool | Update-AzSynapseSparkPool -PackageAction Remove -Package $pool.WorkspacePackages

Manage packages through REST APIs

Manage the workspace packages

With the ability of REST APIs, you can add/delete packages or list all uploaded files of your workspace. See the full supported APIs, please refer to Overview of workspace library APIs.

Manage the Spark pool packages

You can leverage the Spark pool REST API to attach or remove your custom or open source libraries to your Spark pools.

  1. For custom libraries, please specify the list of custom files as the customLibraries property in request body.

    "customLibraries": [
        {
            "name": "samplejartestfile.jar",
            "path": "<workspace-name>/libraries/<jar-name>.jar",
            "containerName": "prep",
            "uploadedTimestamp": "1970-01-01T00:00:00Z",
            "type": "jar"
        }
    ]
    
  2. You can also update your Spark pool libraries by specifying the libraryRequirements property in request body.

    "libraryRequirements": {
          "content": "",
          "filename": "requirements.txt"
    }
