Recently one of my project required a migration process to be run on a large number of records. Ideally, I wanted to run the processing for individual Sitecore items in parallel. Unfortunately, SPE doesn't support "-Parallel" parameter on ForEach-Object, so I had to come up with a different approach. I learnt that PowerShell 7 supports this parameter and figured that it might be possible to combine the PowerShell 7 script with execution of SPE script using remoting. Below is the result of this effort, if you are interested.
There is a function that makes a call to a URL to retrieve an image, downloads it into a folder in Sitecore Data Folder, and uploads it into the Media Library. If the process is successful, the function returns the created media item and image field gets updated with the reference to the newly created image.
Import-Module -Name SPE
$credential = Get-Credential
$session = New-ScriptSession -Username admin -Password b -ConnectionUri https://www-local-9sc.dev.local -Credential $credential
$apiBaseUrl = "https://[service base url]"
$groupEndpoint = $apiBaseUrl
$headers = @{"X-AUTH-TOKEN" = "#############"}
Write-Output "###############################################################"
Write-Output "################# Starting Import #####################"
Write-Output "###############################################################"
while $groupEndpoint -ne $null) {
Write-Output "______________________________________________________________________"
Write-Output $groupEndpoint
Write-Output "__________________________________________________________________________"
$Response = Invoke-RestMethod -Uri $groupEndpoint -Method "GET" -Headers $headers -UseBasicParsing
$groupEndpoint = $Response.meta.next_link
$Response.data | ForEach-Object -Parallel {
