Use Queue peek operations for observation without changing message visibility

Source facts

Microsoft explains that Peek previews messages without dequeuing them or increasing DequeueCount. Receive temporarily hides a message from other processes for the visibility timeout. Permanent deletion requires both the message identifier and its pop receipt. Microsoft Learn

Applicability

This guide applies to a PowerShell-based Azure Queue Storage investigation where the operator needs to decide whether to observe a message or take part in its processing.

DSE recommendation

DSE recommends classifying the operation before running the queue client method. For inspection, choose the documented peek path and restrict the displayed content to what the investigation needs. For a processing test, use a designated test message and document the visibility interval and deletion decision. Keep routine troubleshooting separate from message consumption so the investigator understands which actions can affect the worker’s view of the queue.

Verification

Record which method was called and inspect the resulting message metadata. During a controlled processing test, compare visibility and deletion behavior with the intended sequence. Do not describe a received message as permanently removed unless the delete operation succeeded. Preserve unexpected results with the message identifier while avoiding unnecessary disclosure of message contents.
