Description

Use Cases

1. In the case where user looses data within Atlas, they can get it ingested by using tool like import-hive. With this approach, the user does not get the classifications and the entities associated with them.

2. In case where classifications were inadvertently removed from entities.

Solution

In the scenarios above, currently there isn't a way to know the classification operations performed.

A REST API that would get this information from Atlas' Audit tables would benefit the user.

Approach Guidance

• REST endpoint: Use Atlas' Audit Repository to fetch the audit events. This API should accept a timestamp range so that useful audit events can be fetched.
• REST endpoint: Re-play the audit events to update Atlas.
