Operações de taxa de transferência (RU/s) com o PowerShell para um banco de dados ou grafo para o Azure Cosmos DB – API do Gremlin

APLICA-SE AO: Gremlin

Este exemplo exige o Azure PowerShell Az 5.4.0 ou posterior. Execute Get-Module -ListAvailable Az para ver quais versões estão instaladas. Se é preciso instalar, consulte Instalar o módulo do Azure PowerShell.

Execute Connect-AzAccount para entrar no Azure.

Obter taxa de transferência

# 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

Atualizar a taxa de transferência

# 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
}

Migrar a taxa de transferência

# 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

Limpar a implantação

Após a execução do script de exemplo, o comando a seguir pode ser usado para remover o grupo de recursos e todos os recursos associados a ele.

Remove-AzResourceGroup -ResourceGroupName "myResourceGroup"
