Azure server-side paging

[almahmoud]

For Azure, paging is always handled client-side now, as all pages are iterated through and resources are then wrapped for client-side paging. We could implement server-side paging for Azure: https://github.com/Azure/msrest-for-python/blob/master/msrest/paging.py possibly using the next_link property as a marker?

@almahmoud Can this be closed?

I think paging is still client-side in azure.

Hello, I'm new to open source and i'm interested in solving this issue.Is this issue open. Could you please help in getting started with this project and guide me through this issue. Thanks

Hi @akshatakulkarni25, we are happy to accept contributions. Yes, this issue is still open. For starters, please go through the cloudbridge docs and once you are familiar with how paging is implemented: http://cloudbridge.cloudve.org/en/latest/topics/paging_and_iteration.html please take a look at the aws and google implementations. Then, you need to do something similar for Azure. Please comment on this issue if you have any questions.

The function is performing serverside pagination here for keypair service. Could you help me understand if i have to write this class

[nuwang]

The ServerPagedResultList does not need to be implemented, as the implementation is generic for all cloud providers. The core task will be to find all instances in Azure where a ClientPagedResultList is returned, and investigate whether they can be replaced with a ServerPagedResultList. These will usually be in the list() and find() methods. As you can see in the KeyPair service example, in order to return a ServerPagedResultList, the underlying azure server class should support a limit and a marker, which can then be used to construct a ServerPagedResultList. Most azure server functions support these, and they can be trivially replaced. The ClientPagedResultLists in contrast, only simulate the limit and marker, and are therefore very inefficient, as all records are fetched from the server, and paging is done in the client. Hope this clarifies the issue. Please take a look at the specific azure library methods for more details.

What we call marker in cloudbridge is called a continuation token in Azure: https://learn.microsoft.com/en-us/answers/questions/176750/how-to-use-the-continuationtoken.html
