Azure integration

In this overview, we'll look at the building blocks required to use the Quantemplate API to listen for Dataset Updated events and then extract that dataset to a SQL table.

This video shows the end-to-end process and the remaining documentation will add some technical detail.

Receiving notifications from Quantemplate

1. Follow this guide to create a Runbook and a Webhook
2. Take the webhook URL and follow the notifications example to receive events from Quantemplate

Running a Data Factory Pipeline from a Runbook

Below is an example PowerShell script with inspiration from this guide:

PowerShell

param (
    [object] $WebHookData
)
Write-Output "Starting run book"

if ($WebHookData){
    # Extract the dataset ID from the payload
    $DatasetId = [regex]::match($WebHookData.RequestBody,'datasetId\":\"(d-[^\"]+)').Groups[1].Value
    Write-Output "DatasetId: $DatasetId"
} else {
    Write-Output 'Not webhook'
    $DatasetId = "not-defined"
}

$PipelineName = "QT_fetch_data"
$CheckLoopTime = 5

#Stop on any error!
$ErrorActionPreference = "Stop"
 
#Get and set configs
$CredentialName = Get-AutomationVariable -Name 'ADF-CredentialName'
$ResourceGroupName = Get-AutomationVariable -Name 'ADF-ResourceGroupName'
$DataFactoryName = Get-AutomationVariable -Name 'ADF-DataFactoryName'
$SubscriptionID = Get-AutomationVariable -Name 'ADF-SubscriptionID'
 
Write-Output "$CredentialName, $ResourceGroupName, $DataFactoryName, $SubscriptionID"

#Get credentials
$AzureDataFactoryUser = Get-AutomationPSCredential -Name $CredentialName

Write-Output "Credentials: $AzureDataFactoryUser"
 
try{
    #Use credentials and choose subscription
    Add-AzureRmAccount -Credential $AzureDataFactoryUser | Out-Null
    Write-Output "Added Account"
    Set-AzureRmContext -SubscriptionId $SubscriptionID | Out-Null
    Write-Output "set context"
 
    # Get data factory object
    $df=Get-AzureRmDataFactoryV2 -ResourceGroupName $ResourceGroupName -Name $DataFactoryName
 
    #If exists - run it
    If($df) {
               Write-Output "Connected to data factory $DataFactoryName on $ResourceGroupName as $($AzureDataFactoryUser.UserName)"

               "{""DatasetID"": ""$DatasetId""}" | Out-File -FilePath .\params.json

               Get-Content -Path .\params.json

               $RunID = Invoke-AzureRmDataFactoryV2Pipeline -ResourceGroupName $ResourceGroupName -DataFactoryName $DataFactoryName -PipelineName $PipelineName -ParameterFile .\params.json
               $RunInfo = Get-AzureRmDataFactoryV2PipelineRun -ResourceGroupName $ResourceGroupName -DataFactoryName $DataFactoryName -PipelineRunId $RunID
 
               Write-Output "`nPipeline triggered!"
               Write-Output "RunID: $($RunInfo.RunId)"
               Write-Output "Started: $($RunInfo.RunStart)`n"
 
               $sw =  [system.diagnostics.stopwatch]::StartNew()
               While (($Pipeline = Get-AzureRmDataFactoryV2PipelineRun -ResourceGroupName $ResourceGroupName -DataFactoryName $DataFactoryName -PipelineRunId $RunID |Select -ExpandProperty "Status") -eq "InProgress")
               {
                
                    #Write-Output 
                    $RunInfo = Get-AzureRmDataFactoryV2PipelineRun -ResourceGroupName $ResourceGroupName -DataFactoryName $DataFactoryName -PipelineRunId $RunID
                    Write-Output "`rLast status: $($RunInfo.Status) | Last updated: $($RunInfo.LastUpdated) | Running time: $($sw.Elapsed.ToString('dd\.hh\:mm\:ss'))" #-NoNewline
                    Start-Sleep $CheckLoopTime
               }
               $sw.Stop()
 
               $RunInfo = Get-AzureRmDataFactoryV2PipelineRun -ResourceGroupName $ResourceGroupName -DataFactoryName $DataFactoryName -PipelineRunId $RunID
 
               Write-Output "`nFinished running in $($sw.Elapsed.ToString('dd\.hh\:mm\:ss'))!"
               Write-Output "Status:"
               Write-Output $RunInfo.Status
 
               if ($RunInfo.Status -ne "Succeeded"){                    
                    throw "There was an error with running pipeline: $($RunInfo.PipelineName). Returned message was:`n$($RunInfo.Message)"
               }
    }
}
Catch{
    Throw
}

Data Factory Copy Pipeline

In this example, the pipeline consists of two simple steps:

• A Web Activity to use the client-id and client-secret to authenticate with Quantemplate
• A Copy Activity to fetch the data from Quantemplate and to write that to a SQL DB instance

👍

Prerequisite: Azure SQL DB Instance

For this step you will require the SQL DB instance to have been created within your Azure account and for the Data Factory to have the required credentials to write to that instance.

This Azure guide details the steps required.

Login Web Activity

The configuration for this activity can be obtained from the Setting Up a Connection example.
URL: https://accounts.prod.quantemplate.com/auth/realms/qt/protocol/openid-connect/token
Method : POST
Header: Content-Type : application/x-www-form-urlencoded
Body: grant_type=client_credentials&client_id=@{variables('ClientID')}&client_secret=@{variables('ClientSecret')}

Copy data Activity

Source data from Quantemplate

This guide provides a good overview of the steps required to configure the Copy data Activity to fetch data from a service like Quantemplate.
The Download Dataset endpoint description defines the URL and parameters required.

Write data to SQL DB

This guide details how to configure the "Sink" part of the Copy Activity to write the data to the DB.
