Operasi Throughput (RU/s) dengan PowerShell untuk keyspace atau tabel untuk API Azure Cosmos DB - Cassandra

BERLAKU UNTUK: Cassandra 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 keyspace or table throughput
# --------------------------------------------------
# Variables - ***** SUBSTITUTE YOUR VALUES *****
$resourceGroupName = "myResourceGroup" # Resource Group must already exist
$accountName = "myaccount" # Must be all lower case
$keyspaceName = "mykeyspace" # Keyspace with shared throughput
$tableName = "mytable" # Table with dedicated throughput
# --------------------------------------------------

Write-Host "Get keyspace shared throughput"
Get-AzCosmosDBCassandraKeyspaceThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -Name $keyspaceName

Write-Host "Get table dedicated throughput"
Get-AzCosmosDBCassandraTableThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -KeyspaceName $keyspaceName `
    -Name $tableName

Perbarui throughput

# Reference: Az.CosmosDB | https://docs.microsoft.com/powershell/module/az.cosmosdb
# --------------------------------------------------
# Purpose
# Update table throughput
# --------------------------------------------------
# Variables - ***** SUBSTITUTE YOUR VALUES *****
$resourceGroupName = "myResourceGroup" # Resource Group must already exist
$accountName = "myaccount" # Must be all lower case
$keyspaceName = "mykeyspace"
$tableName = "mytable"
$newRUs = 500
# --------------------------------------------------
$throughput = Get-AzCosmosDBCassandraTableThroughput -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -KeyspaceName $keyspaceName -Name $tableName

$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-AzCosmosDBCassandraTableThroughput -ResourceGroupName $resourceGroupName `
        -AccountName $accountName -KeyspaceName $keyspaceName `
        -Name $tableName -Throughput $newRUs
}

Migrasikan throughput

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

Write-Host "Migrate keyspace with standard throughput to autoscale throughput."
Invoke-AzCosmosDBCassandraKeyspaceThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -Name $keyspaceName -ThroughputType Autoscale

Write-Host "Migrate keyspace with autoscale throughput to standard throughput."

Invoke-AzCosmosDBCassandraKeyspaceThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -Name $keyspaceName -ThroughputType Manual

Write-Host "Migrate table with standard throughput to autoscale throughput."
Invoke-AzCosmosDBCassandraTableThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -KeyspaceName $keyspaceName -Name $tableName -ThroughputType Autoscale

Write-Host "Migrate table with autoscale throughput to standard throughput."
Invoke-AzCosmosDBCassandraTableThroughputMigration -ResourceGroupName $resourceGroupName `
    -AccountName $accountName -KeyspaceName $keyspaceName -Name $tableName -ThroughputType Manual

Membersihkan penyebaran

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

Remove-AzResourceGroup -ResourceGroupName "myResourceGroup"

Penjelasan skrip

Skrip ini menggunakan perintah berikut. Setiap perintah dalam tabel menautkan ke dokumentasi perintah tertentu.

Perintah	Catatan
Azure Cosmos DB
Get-AzCosmosDBCassandraKeyspaceThroughput	Mendapatkan nilai throughput dari Cassandra API Keyspace.
Get-AzCosmosDBCassandraTableThroughput	Mendapatkan nilai throughput dari Tabel Cassandra API.
Update-AzCosmosDBCassandraKeyspaceThroughput	Memperbarui nilai throughput dari Cassandra API Keyspace.
Update-AzCosmosDBCassandraTableThroughput	Memperbarui nilai throughput Dari Tabel Cassandra API.
Invoke-AzCosmosDBCassandraKeyspaceThroughputMigration	Melakukan migrasi throughput untuk Cassandra API Keyspace.
Invoke-AzCosmosDBCassandraTableThroughputMigration	Melakukan migrasi throughput untuk Tabel Cassandra API.
Grup Sumber Daya Azure
Remove-AzResourceGroup	Menghapus grup sumber daya termasuk semua sumber daya berlapis.
