GetThroughput

# 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

Mettre à jour le débit

# 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
}

Migrer le débit

# 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
