Operasi Throughput (RU/s) dengan PowerShell untuk database atau grafik untuk Azure Cosmos DB - Gremlin API

BERLAKU UNTUK: Gremlin API

Catatan

Artikel ini menggunakan modul Azure Az PowerShell, yang merupakan modul PowerShell yang direkomendasikan untuk berinteraksi dengan Azure. Untuk mulai menggunakan modul Az PowerShell, 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.

Dapatkan throughput

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

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

Write-Host "Get graph dedicated throughput"
Get-AzCosmosDBGremlinGraphThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName `
    -Name $graphName

Perbarui throughput

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

$throughput = Get-AzCosmosDBGremlinGraphThroughput `
    -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName `
    -Name $graphName

$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-AzCosmosDBGremlinGraphThroughput -ResourceGroupName $resourceGroupName `
        -AccountName $accountName -DatabaseName $databaseName `
        -Name $graphName -Throughput $newRUs
}

Migrasikan throughput

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

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

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

Write-Host "Migrate graph with standard throughput to autoscale throughput."
Invoke-AzCosmosDBGremlinGraphThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName -Name $graphName -ThroughputType Autoscale

Write-Host "Migrate graph with autoscale throughput to standard throughput."
Invoke-AzCosmosDBGremlinGraphThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -DatabaseName $databaseName -Name $graphName -ThroughputType Manual

Membersihkan penyebaran

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