Configure depth overflow value - Start-Job - powershell

Question

I have a recursive function that is executed around 750~ times - iterating over XML files and processing. The code is running using Start-Job
Example below:
$job = Start-Job -ScriptBlock {
function Test-Function {
Param
(
$count
)
Write-Host "Count is: $count"
$count++
Test-Function -count $count
}
Test-Function -count 1
}
Output:
$job | Receive-Job
Count is: 224
Count is: 225
Count is: 226
Count is: 227
The script failed due to call depth overflow.
The depth overflow occurs at 227 consistently on my machine. If I remove Start-Job, I can reach 750~ (and further). I am using jobs for batch processing.
Is there a way to configure the depth overflow value when using Start-Job?
Is this a limitation of PowerShell Jobs?

Answer 1

I can't answer about the specifics of call depth overflow limitations in PS 5.1 / 7.2 but you could do your recursion based-off a Queue within the job.
So instead of doing the recursion within the function, you do it from outside (still within the job though).
Here's what this look like.
$job = Start-Job -ScriptBlock {
$Queue = [System.Collections.Queue]::new()
function Test-Function {
Param
(
$count
)
Write-Host "Count is: $count"
$count++
# Next item to process.
$Queue.Enqueue($Count)
}
# Call the function once
Test-Function -count 1
# Process the queue
while ($Queue.Count -gt 0) {
Test-Function -count $Queue.Dequeue()
}
}
Reference:
.net Queue class

Not an answer that would solve the problem but rather an informative one. You could use an instance of the PowerShell SDK's [powershell] class instead of Start-Job, which can handle more levels of recursion (by a big amount) in case it helps, here are my results:

Code to reproduce
$instance = [powershell]::Create().AddScript({
function Test-Function {
Param($count)
Write-Host "Count is: $count"
$count++
Test-Function -count $count
}
Test-Function -count 1
})
$handle = $instance.BeginInvoke()
do {
$done = $handle.AsyncWaitHandle.WaitOne(500)
} until($done)
$instance.Streams.Information[-1]
$instance.Dispose()
