Description

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.
