What best describes the change feed option in Azure Blob Storage Service?

The change feed option in Azure Blob Storage Service provides a read-only record of updates made to the blobs. This feature is particularly useful for tracking changes over time, as it allows users to efficiently monitor the state of the blobs without needing to maintain complex logging or tracking mechanisms themselves. It generates a chronological log of events such as insertions, updates, and deletions, making it an excellent tool for applications that require data consistency or state tracking.

This capability is beneficial in various scenarios, such as extracting transformations, auditing changes, or responding to updates in applications that depend on blob data. By utilizing the change feed, developers and data engineers can build performant and efficient data processing workflows, as they can process only the changed content instead of the entire dataset repeatedly.
