。 在ForEach-Object -Parallel块内,函数的递归调用会出现问题,因为并行块内无法识别函数。这是因为在并行处理中,多个任务被同时执行,而函数调用需要通过堆栈来跟踪执行流程。在并行...
Parallel.For 和 Parallel.ForEach结构就是这样做的。目标：编写一个shell脚本，以便能够将mongoDb中的数...
这个版本实现了管道的并行化,即 ForEach-Object cmdlet 增加了-Parallel 参数: ForEach-Object -Parallel <ScriptBlock> [ -ThrottleLimit ] [ ... ] 例: PS> $logNames = 'Security', 'Application', 'System', 'Windows PowerShell' PS> $logEntries = $logNames | ForEach-Object -Parallel { Get-...
Database $Workload | ForEach-Object -Parallel { $ComputerName = $($_.Instance).Split('\')[0] $SqlServer = $($_.Instance) $Database = $($_.Database) Invoke-Command -ComputerName $ComputerName -AsJob -JobName $Database -ScriptBlock ${Function:Start-UpdateStatistics} ...
0..5 | ForEach-Object -ThrottleLimit 6 -Parallel { $localAddToMe = $using:addToMe $psvar = $using:psvar Write-Host $_ if($_ -gt 3) { [System.Threading.Monitor]::Enter($psvar) $psvar.Value = $true [System.Threading.Monitor]::Exit($psvar) ...
即使在使用$using:关键字 (keyword) 的情况下Foreach-Object -Parallel,也不支持PipelineVariable通用参数变量。 示例17:在嵌套并行脚本 ScriptBlockSet 中传递变量 可以在作用域的脚本块外部Foreach-Object -Parallel创建变量,并在脚本块$using中使用该变量和关键字 (keyword) 。
PowerShell 7.0 Preview 3 is now available with a new ForEach-Object Parallel Experimental feature. This feature is a great new tool for parallelizing work, but like any tool, it has its uses and drawbacks. This article describes this new feature, how it works, when to use it and when ...

Also,https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/foreach-object?view=powershell-7.2#example-11--run-slow-script-in-parallel-batches This suggest that my $_. should work. I think I'm lost in translation😄...
You can still create a new runspace for each iteration using the UseNewRunspace switch. By default, the parallel scriptblocks use the current working directory of the caller that started the parallel tasks. For more information, see the NOTES section of this articl...
