How to verify even hub is immutable

Question

I need to provide proof to the Auditor that the azure event hub is immutable and append only. He needs proof based on config setting or code, not based on event hub doc. How can we provide the same?

Hello Shafi, Welcome to MS Q&A

I think there is no specific configuration setting or code that can provide proof that Azure Event Hub is immutable and append-only. The immutability and append-only nature of Azure Event Hub is achieved through the use of immutability policies, which can be set at the container or version level. Time-based retention policies and legal hold policies prevent write and delete operations while they are in effect. When a time-based retention policy is set, objects can be created and read, but not modified or deleted. After the retention period has expired, objects can be deleted but not overwritten. A legal hold stores immutable data until the legal hold is explicitly cleared.

For more detailed information, you can refer to the following resources:

• Kafka Streams for Azure Event Hubs
• Availability and consistency in Event Hubs
• Store business-critical blob data with immutable storage in a write once, read many (WORM) state

Please let me know if any further question

Kindly accept answer if it helps
