What is the fastest way to get the LastModified Timestamp of a Recent Blob in the Azure Storage Container?

Question

I would like to know if there is a better way to get the LastModified timestamp of a the recent blob. One way to find the last recent blob in Azure Storage Container is to traverse through all the blobs and sort the results in Descending Order using the Last Modified timestamp value.

But then if the container has large set of files then this operation may take longer. Do we have any better ways to get the recent blob and its Last Modified Timestamp

@Varun Thank you for reaching out to Microsoft Q&A. I understand that you want to get the Lastmodified Timestamp of a recent blob in Azure and want to know the fastest way to get it.

You can get it as discussed in this thread- https://social.msdn.microsoft.com/Forums/en-US/90465e17-5f85-4075-92df-248b8abe7052/get-most-recent-last-modified-file-name-from-containers-subfolder?forum=windowsazuredata

# Connect to Azure with an interactive dialog for sign-in  
#Connect-AzAccount  
$container_name = 'containername'  
$connection_string = 'DefaultEndpointsProtocol=https;AccountName=AccName;AccountKey=AccKey'  
$storage_account = New-AzStorageContext -ConnectionString $connection_string  
# Get the blobs list and then sort them by last modified date descending  
$blobs = Get-AzStorageBlob -Container $container_name -Context $storage_account -Blob *.bak | sort @{expression="LastModified";Descending=$true}  
$latestBlob = $blobs[0]  
write $latestBlob.Name  

Does this help or are you looking for something more? Please let me know. Thanks!
