Hi All, CarbonData allows to store the data incrementally and do the Update/Delete operations on the stored data. But the user always can access the latest state of data at that point of time.
In the current system, it is not possible to access the old version of data. And it is not possible to rollback to the old version in case of some issues in current version data. This proposal adds the automatic versioning of data that we store and we can access any historical version of that data. The design is attached on the jira https://issues.apache.org/jira/browse/CARBONDATA-3500 Please check it. -- Thanks & Regards, Ravindra.
