--------------------------------------
Summary: Export & Import Process: Add Data to AtlasCluster About
Last Successful Import
Key: ATLAS-2814
URL: https://issues.apache.org/jira/browse/ATLAS-2814
Project: Atlas
Issue Type: Improvement
Components: atlas-core
Affects Versions: 0.8.3
Reporter: Ashutosh Mestry
Assignee: Ashutosh Mestry
Fix For: 0.8.3
*Background*
Scenario: Couple of Atlas clusters are setup such that incremental export and
import is setup via some custom program. Example, Cluster _cl1_ exports does
incremental export and the output is imported into cluster _cl2_.
It may be worth while to maintain some information about the last successful
import. This way the next incremental export will have correct parameters for
its export.
*Approach Guidance*
* Create a new model, say _AtlasSyncInfo_, that stores information about top
level entity used for export and the timestamp that should be used for
subsequent incremental export.
* ++Utilize _AtlasCluster_'s _additionalInfo_ fields to store serialized
version of _AtlasSyncInfo_.
* Provide REST APIs for retrieval of this information.
