Is there option to auto terminate Azure SQL DW - azure

Question

I am using Azure SQL DW which costs more per an hour. So I want to know is there option for auto terminate SQL DW after an hour or so?

Answer 1

You can pause the Azure Data warehouse and then you only pay for the storage used.
You can automate pausing your DWH by using an Azure automation account and a runbook.
This blog explains the process:

Yes, it is possible.
To save costs, you can pause and resume compute resources on-demand. For example, if you won't be using the database during the night and on weekends, you can pause it during those times, and resume it during the day. You won't be charged for DWUs while the database is paused.
When you pause a database:
Compute and memory resources are returned to the pool of available resources in the data center
DWU costs are zero for the duration of the pause.
Data storage is not affected and your data stays intact.
SQL Data Warehouse cancels all running or queued operations.
To pause a database, use the Suspend-AzureRmSqlDatabase cmdlet.
Suspend-AzureRmSqlDatabase –ResourceGroupName "ResourceGroup1" `
–ServerName "Server01" –DatabaseName "Database02"
To start a database, use the Resume-AzureRmSqlDatabase cmdlet.
Resume-AzureRmSqlDatabase –ResourceGroupName "ResourceGroup1" `
–ServerName "Server01" -DatabaseName "Database02"
More information please refer to this official document.
As Markus Bohse said, you also could use Automation to do this.
Note: You also could write a runbook to start your database.
Update: If you want to use java to do this, please refer to this API document.
public void pauseDataWarehouse()
Update:
You also could Rest API to do this. See this link

Answer 3

You can use runbooks or powershell script to pause dn resume SQL DWH.
Powershell script is below. If you would like "runbook" let me know
