-----------------------------------
Attachment: ATLAS-3762-Improve-Edge-creator-using-Genuine-iterat.patch
> Entity Creation: Improve Vertices and Edges Fetch Using Genuine Iterators
> -------------------------------------------------------------------------
>
> Key: ATLAS-3762
> URL: https://issues.apache.org/jira/browse/ATLAS-3762
> Project: Atlas
> Issue Type: Improvement
> Reporter: Ashutosh Mestry
> Assignee: Ashutosh Mestry
> Priority: Major
> Attachments:
> ATLAS-3762-Improve-Edge-creator-using-Genuine-iterat.patch
>
>
> *Background*
> One of the earlier commits replaced vertices and edges fetch with
> _StreamSupport.stream_. This uses _Collect(toList),_ which causes all
> contents to be fetched.
> Using this causes large amount of data to be fetched.
> *Solution*
> Switch to iterators that will use lazy loading.
> *Minor Refactoring*
> Change the _getEdge_ to iterate on smaller dataset.
> [~sidharthkmishra] Thanks for this simple but effective fix.
