> Project: Atlas
> Issue Type: Improvement
> Components: atlas-core
> Affects Versions: trunk
> Reporter: Ashutosh Mestry

> *Background*
> When creating entities with Atlas at scale, few inefficiencies were observed.
> They were:
> * _GraphHelper.getAdjacentEdgesByLabel_: The existing approach results in
> high memory usage. The method could use graph api that already exists.
> * _AtlasRelationshipStoreV2.getRelationshipEdge_: This does full vertex
> comparison. This is expensive.
> * Edge label is not index. Indexing this will improve speed of edge by label
> lookup.
> *Solution*
> Profile Atlas with (using metrics) to establish baseline.
> Use the fixes mentioned to the places above and profile.
