Storage queue receive_messages unexpected behaviour

[kobibarhanin]

• Package Name: azure-storage-queue
• Package Version: 12.1.3
• Operating System: mac / linux
• Python Version: 3.8.3

Describe the bug
When retrieving messages from a storage queue with:
receive_messages(messages_per_page=<SOME NUMBER>)
I get the entire queue back regardless of SOME NUMBER.
this is in contrast with expected behaviour and this method's docs.

To Reproduce
Steps to reproduce the behavior:

1. run receive_messages on some queue with kw arg messages_per_page.

Expected behavior
return of messages_per_page messages (if exists).

Additional context
This is not additional context - but I'm also facing a weird issue that whenever I run receive_messages I have to wait for about 30 seconds to run it again to get results (if I run it sooner I get no results back) - anyone knows anything about this?

Thanks!

Hi @kobibarhanin, please refer to #14665, let me know if this helps :)

Thanks for the response!

I was able to squeeze out a strategy but I really think this should be better implemented - no reason to not enable a simpler approach to retrieve a fixed amount of elements from a hosted queue.

Thanks again.

Hi @kobibarhanin, yea it seems this is a common misinterpretation by users. We added a sample recently to also better help users understand how this method operates better here:

azure-sdk-for-python/sdk/storage/azure-storage-queue/samples/queue_samples_message.py

Line 149 in 1b2450b

def list_message_pages(self):

and here

azure-sdk-for-python/sdk/storage/azure-storage-queue/samples/queue_samples_message.py

Line 108 in 1b2450b

def send_and_receive_messages(self):

Let me know what you think of those samples :)
