> --------------------------------------------------

> Key: ATLAS-2738
> URL: https://issues.apache.org/jira/browse/ATLAS-2738
> Project: Atlas
> Issue Type: Improvement
> Components: atlas-core
> Affects Versions: 0.8.3
> Reporter: Ashutosh Mestry
> Assignee: Ashutosh Mestry
> Priority: Major
> Fix For: 0.8.3
>
> Attachments: ATLAS-2738-Support-for-incremental-export.patch
>
>
> *Background*
> Use case: Export & Import process is used to synchronize data between
> clusters.
> Data is exported from a cluster and imported into another cluster. Subsequent
> exports should only contain entities that have been created or updated since
> the last export. This helps makes the export process quicker and the payload
> will be smaller.
> *Implementation Approach*
> Add new _fetchType_: _incremental,_ with additional parameter _fromTime_
> which is a timestamp. During Export process, entities' that have
> ___modificationTimestamp_ greater than _fromTime_ would be included in the
> export.
