Subject [jira] [Created] (ATLAS-4019) Audit improvement to store only delta
Date Wed, 11 Nov 2020 03:54:00 GMT
Deep Singh created ATLAS-4019:
---------------------------------

             Summary: Audit improvement to store only delta
                 Key: ATLAS-4019
                 URL: https://issues.apache.org/jira/browse/ATLAS-4019
             Project: Atlas
          Issue Type: Improvement
          Components: atlas-intg
            Reporter: Deep Singh
            Assignee: Deep Singh


For any entity operation after the entity is created - e.g. add a column, update an attribute.
- the entire updated entity is saved in Hbase audits (for each operation). Only the delta
between two entity states needs to be stored.

Update routine could be called for an individual entity or for a list of entities. Update-request
may contain a full entity object or partial object(with only updated attributes or relations).
There could be updates in entity core attributes, relationship attributes, custom attributes,
or associated classifications. In all the cases today we store the entire updated entity in
Hbase audits. Improvement is required so that only the updated information is stored in Hbase
audits instead of the entire entity object.
