> *Background*
> [ATLAS-3762|] introduced edge creation
improvement by improving on edge existence check.
> The same change could be applied to another area within the implementation.
> *Investigation*
> This was discovered as part of volume testing done for high-volume import. This included
importing over 100M entities. Various parts of the entity creation process had probes added
to check for performance.
> During this investigation the edge creation was doing the same existence check that was
addressed in earlier fixes. Re-using the same implementation showed marked improvement in
entity creation.
> These were the parameters used for during import.
> Node configuration: 128 GB RAM, 40 cores.
> {code:java}
> atlas.migration.mode.batch.size=1500
