从系统主题中删除事件订阅

Question

我的powershell代码太慢了，无法从系统主题中删除所有事件订阅。

# Get all event subscription names associated with the system topic
$subscriptions = az eventgrid system-topic event-subscription list --system-topic-name $systemTopicName --resource-group $resourceGroupName --query "[].name" -o tsv

# Iterate through each subscription and delete it
foreach ($sub in $subscriptions) {
    Write-Host "Deleting event subscription: $sub"
    az eventgrid system-topic event-subscription delete --system-topic-name $systemTopicName --resource-group $resourceGroupName --name $sub --yes
}

有没有更快的方法来删除所有事件订阅？

ForEach-Object -Parallel 可从 Powershell v7.0 获取，可用于并行化工作。

尝试这样的事情（未经测试）：

# Get all event subscription names associated with the system topic
$subscriptions = az eventgrid system-topic event-subscription list --system-topic-name $systemTopicName --resource-group $resourceGroupName --query "[].name" -o tsv

# Iterate through each subscription and delete it
$subscriptions | Foreach-Object -Parallel {
    Write-Host "Deleting event subscription: $sub"

    az eventgrid system-topic event-subscription delete \
      --system-topic-name $systemTopicName \
      --resource-group $resourceGroupName \
      --name $_ \
      --yes
} -ThrottleLimit 5 # ThrottleLimit parameter limits the number of parallel scripts
