使用 PowerShell 對 Azure Cosmos DB for NoSQL 的資料庫或容器執行輸送量 (RU/秒) 作業

適用於：NoSQL

注意

建議您使用 Azure Az PowerShell 模組來與 Azure 互動。 若要開始使用，請參閱 安裝 Azure PowerShell。 若要了解如何移轉至 Az PowerShell 模組，請參閱將 Azure PowerShell 從 AzureRM 移轉至 Az。

此範例需要 Azure PowerShell Az 5.4.0 或更新版本。 執行 Get-Module -ListAvailable Az 可查看已安裝的版本。 如果您需要安裝，請參閱安裝 Azure PowerShell 模組。

執行 Connect-AzAccount 來登入 Azure。

取得輸送量

# Reference: Az.CosmosDB | https://docs.microsoft.com/powershell/module/az.cosmosdb
# --------------------------------------------------
# Purpose
# Get database or container throughput
# --------------------------------------------------
# Variables - ***** SUBSTITUTE YOUR VALUES *****
$resourceGroupName = "myResourceGroup" # Resource Group must already exist
$accountName = "myaccount" # Must be all lower case
$databaseName = "myDatabase"
$containerName = "myContainer"
# --------------------------------------------------

Write-Host "Get database shared throughput - if none provisioned, will return error."
Get-AzCosmosDBSqlDatabaseThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -Name $databaseName

Write-Host "Get container dedicated throughput - if none provisioned, will return error."
Get-AzCosmosDBSqlContainerThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName `
    -Name $containerName

更新輸送量

# Reference: Az.CosmosDB | https://docs.microsoft.com/powershell/module/az.cosmosdb
# --------------------------------------------------
# Purpose
# Update container throughput
# --------------------------------------------------
# Variables - ***** SUBSTITUTE YOUR VALUES *****
$resourceGroupName = "myResourceGroup" # Resource Group must already exist
$accountName = "myaccount" # Must be all lower case
$databaseName = "myDatabase"
$containerName = "myContainer"
$newRUs = 500
# --------------------------------------------------

$throughput = Get-AzCosmosDBSqlContainerThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName -Name $containerName

$currentRUs = $throughput.Throughput
$minimumRUs = $throughput.MinimumThroughput

Write-Host "Current throughput is $currentRUs. Minimum allowed throughput is $minimumRUs."

if ([int]$newRUs -lt [int]$minimumRUs) {
    Write-Host "Requested new throughput of $newRUs is less than minimum allowed throughput of $minimumRUs."
    Write-Host "Using minimum allowed throughput of $minimumRUs instead."
    $newRUs = $minimumRUs
}

if ([int]$newRUs -eq [int]$currentRUs) {
    Write-Host "New throughput is the same as current throughput. No change needed."
}
else {
    Write-Host "Updating throughput to $newRUs."

    Update-AzCosmosDBSqlContainerThroughput -ResourceGroupName $resourceGroupName `
        -AccountName $accountName -DatabaseName $databaseName `
        -Name $containerName -Throughput $newRUs
}

遷移輸送量

# Reference: Az.CosmosDB | https://docs.microsoft.com/powershell/module/az.cosmosdb
# --------------------------------------------------
# Purpose
# Migrate a database or container to autoscale or standard (manual) throughput
# --------------------------------------------------
# Variables - ***** SUBSTITUTE YOUR VALUES *****
$resourceGroupName = "myResourceGroup" # Resource Group must already exist
$accountName = "myaccount" # Must be all lower case
$databaseName = "myDatabase"
$containerName = "myContainer"
# --------------------------------------------------

Write-Host "Migrate database with standard throughput to autoscale throughput."
Invoke-AzCosmosDBSqlDatabaseThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -Name $databaseName -ThroughputType Autoscale

Write-Host "Migrate database with autoscale throughput to standard throughput."
Invoke-AzCosmosDBSqlDatabaseThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -Name $databaseName -ThroughputType Manual

Write-Host "Migrate container with standard throughput to autoscale throughput."
Invoke-AzCosmosDBSqlContainerThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName -Name $containerName -ThroughputType Autoscale

Write-Host "Migrate container with autoscale throughput to standard throughput."
Invoke-AzCosmosDBSqlContainerThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName -Name $containerName -ThroughputType Manual

清除部署

在執行過指令碼範例之後，您可以使用下列命令來移除資源群組和所有與其相關聯的資源。

Remove-AzResourceGroup -ResourceGroupName "myResourceGroup"

指令碼說明

此指令碼會使用下列命令。 下表中的每個命令都會連結至命令特定的文件。
