ATLAS-4019: audit improvement to store only delta
Signed-off-by: Madhan Neethiraj <[email protected]>
> 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
> Priority: Major
>
> 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.
