---------------------------------
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.
