Labels: release-notes (was: )
> Export Service: Incremental Export: Next Increment Should Consider All
> Existing Request Contexts
> ------------------------------------------------------------------------------------------------
>
> Key: ATLAS-2862
> URL: https://issues.apache.org/jira/browse/ATLAS-2862
> Project: Atlas
> Issue Type: Bug
> Components: atlas-core
> Affects Versions: 0.8.3
> Reporter: Ashutosh Mestry
> Assignee: Ashutosh Mestry
> Priority: Major
> Labels: release-notes
> Fix For: 0.8.3, 1.2.0, 2.0.0
>
>
> *Background*
> When performing incremental Export, the existing implementation computes the
> next increment timestamp by finding the maximum value of exported entities'
> _modificationTimestamp_. This may work for majority of cases, however it has
> a drawback.
> Consider a scenario where export is in progress and one of the entities that
> has already been written to the zip stream is modified by another request,
> this will be missed from the the subsequent export operation.
> *Solution Approach*
> * Compute timestamps by enumerating all the requests in progress and finding
> the earliest request. If no requests in progress, return current timestamp.
> * Use the timestamp from step above for the change timestamp in
> _AtlasExportResult_.
