Get count of rows in a partition of an azure table using Azure PowerShell - azure-powershell

Question

I would like to get count of rows in a partition. I have the code for getting the total count of rows. How can I alter it to get count for a particular partition. Also I am getting warning for fetching count of all rows and not getting the count on powershell window. Is there any documentation on this?
function GetTable($connectionString, $tableName)
{
$context = New-AzureStorageContext -ConnectionString $connectionString
$azureStorageTable = Get-AzureStorageTable $tableName -Context $context
$azureStorageTable
}
function GetTableCount($table)
{
#Create a table query.
$query = New-Object Microsoft.WindowsAzure.Storage.Table.TableQuery
#Define columns to select.
$list = New-Object System.Collections.Generic.List[string]
$list.Add("PartitionKey")
#Set query details.
$query.SelectColumns = $list
#Execute the query.
$entities = $table.CloudTable.ExecuteQuery($query)
($entities | measure).Count
}
$connectionString = "xyz"
$table = GetTable $connectionString SystemAudit
GetTableCount $table

There is a function Get-AzureStorageTableRowByPartitionKey you could use, and the following is the sample code
function GetTable($connectionString, $tableName)
{
$context = New-AzureStorageContext -ConnectionString $connectionString
$azureStorageTable = Get-AzureStorageTable $tableName -Context $context
$azureStorageTable
}
function GetTableCount($table)
{
$list = Get-AzureStorageTableRowByPartitionKey -table $table –partitionKey “storage” | measure
$list.Count
}
Import-Module AzureRmStorageTable
$connectionString = xyz"
$table = GetTable $connectionString <yourTableName>
GetTableCount $table
