Operasi throughput (RU/s) dengan PowerShell untuk database atau koleksi untuk Azure Cosmos DB untuk MongoDB

BERLAKU UNTUK: MongoDB

Catatan

Sebaiknya Anda menggunakan modul Azure Az PowerShell untuk berinteraksi dengan Azure. Untuk memulai, lihat Menginstal Azure PowerShell. Untuk mempelajari cara bermigrasi ke modul Az PowerShell, lihat Memigrasikan Azure PowerShell dari AzureRM ke Az.

Sampel ini memerlukan Azure PowerShell Az 5.4.0 atau yang lebih baru. Jalankan Get-Module -ListAvailable Az untuk melihat versi mana yang dipasang. Jika Anda perlu memasang, lihat Pasang modul Azure PowerShell.

Jalankan Connect-AzAccount untuk masuk ke Azure.

Mendapatkan throughput

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

Write-Host "Get database shared throughput"
Get-AzCosmosDBMongoDBDatabaseThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -Name $databaseName

Write-Host "Get collection dedicated throughput"
Get-AzCosmosDBMongoDBCollectionThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName `
    -Name $collectionName

Perbarui throughput

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

$throughput = Get-AzCosmosDBMongoDBCollectionThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName -Name $collectionName

$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-AzCosmosDBMongoDBCollectionThroughput -ResourceGroupName $resourceGroupName `
        -AccountName $accountName -DatabaseName $databaseName `
        -Name $collectionName -Throughput $newRUs
}

Migrasikan throughput

# Reference: Az.CosmosDB | https://docs.microsoft.com/powershell/module/az.cosmosdb
# --------------------------------------------------
# Purpose
# Migrate a database or collection 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"
$collectionName = "myCollection"
# --------------------------------------------------

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

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

Write-Host "Migrate collection with standard throughput to autoscale throughput."
Invoke-AzCosmosDBMongoDBCollectionThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName -Name $collectionName -ThroughputType Autoscale

Write-Host "Migrate collection with autoscale throughput to standard throughput."
Invoke-AzCosmosDBMongoDBCollectionThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName -Name $collectionName -ThroughputType Manual

Bersihkan penyebaran

Setelah sampel skrip dijalankan, perintah berikut dapat digunakan untuk menghapus grup sumber daya dan semua sumber daya yang terkait.

Remove-AzResourceGroup -ResourceGroupName "myResourceGroup"
