AZ-204 Certification: Change feed support in Azure Blob Storage

Posted by Derek Zhu on Aug 4, 2020 8:30:18 AM

The purpose of the change feed is to provide transaction logs of all changes that occur to the blobs and their metadata in your storage account. The change feed provides an orderedguaranteeddurableimmutableread-only log of these changes. Client applications can read these logs at any time, either in streaming or in batch mode. The change feed enables you to build efficient and scalable solutions, processing change events that occur in your Blob Storage account at a low cost.

Usage Scenario:

Question: You are a developer and you want to write an application to read the transaction logs of all changes that occur to the blobs and their metadata in the storage account. The changes must be in the order in which they occurred, include only create, update, delete and copy operations and be retained for compliance reasons. You need to process the transaction logs asynchronously. What should you do?

Answer: Enable the change feed on the storage account and process all changes for available events.
