REST APIs for managing compute for dedicated SQL pool (formerly SQL DW) in Azure Synapse Analytics.

Note

The REST APIs that are described in this article are for standalone dedicated SQL pools (formerly SQL DW) and are not applicable to a dedicated SQL pool in an Azure Synapse Analytics workspace. For information about REST APIs to use specifically for an Azure Synapse Analytics workspace, see Azure Synapse Analytics workspace REST API.

Scale compute

To change the data warehouse units, use the Create or Update Database REST API. The following example sets the data warehouse units to DW1000 for the database MySQLDW, which is hosted on server MyServer. The server is in an Azure resource group named ResourceGroup1.

PUT https://management.azure.com/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.Sql/servers/{server-name}/databases/{database-name}?api-version=2020-08-01-preview HTTP/1.1
Content-Type: application/json; charset=UTF-8

{
    "location": "West Central US",
    "sku": {
        "name": "DW200c"
    }
}

Pause compute

To pause a database, use the Pause Database REST API. The following example pauses a database named Database02 hosted on a server named Server01. The server is in an Azure resource group named ResourceGroup1.

POST https://management.azure.com/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.Sql/servers/{server-name}/databases/{database-name}/pause?api-version=2020-08-01-preview HTTP/1.1

Resume compute

To start a database, use the Resume Database REST API. The following example starts a database named Database02 hosted on a server named Server01. The server is in an Azure resource group named ResourceGroup1.

POST https://management.azure.com/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.Sql/servers/{server-name}/databases/{database-name}/resume?api-version=2020-08-01-preview HTTP/1.1

Check database state

Note

Currently Check database state might return ONLINE while the database is completing the online workflow, resulting in connection errors. You might need to add a 2 to 3 minutes delay in your application code if you are using this API call to trigger connection attempts.

GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Sql/servers/{serverName}/databases/{databaseName}?api-version=2020-08-01-preview

Get maintenance schedule

Check the maintenance schedule that has been set for a dedicated SQL pool (formerly SQL DW).

GET https://management.azure.com/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.Sql/servers/{server-name}/databases/{database-name}/maintenanceWindows/current?maintenanceWindowName=current&api-version=2017-10-01-preview HTTP/1.1

Set maintenance schedule

To set and update a maintenance schedule on an existing dedicated SQL pool (formerly SQL DW).

PUT https://management.azure.com/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.Sql/servers/{server-name}/databases/{database-name}/maintenanceWindows/current?maintenanceWindowName=current&api-version=2017-10-01-preview HTTP/1.1

{
    "properties": {
        "timeRanges": [
                {
                                "dayOfWeek": "Saturday",
                                "startTime": "00:00",
                                "duration": "08:00",
                },
                {
                                "dayOfWeek": "Wednesday",
                                "startTime": "00:00",
                                "duration": "08:00",
                }
                ]
    }
}
