> *Background*
> For Import replication options that includes _skipLineage_ and
> _replicatedTo_, __ current implementation uses one entity-at-time import
> approach.
> This approach can be end up taking long time to import for large payloads.
> *Solution*
> * Use an approach that allows for entity of a type to be concurrently
> created.
> * This assumes that the incoming stream of entities to be imported is
> topologically sorted (where parent entities appear before the child entities).
> * Create entities of a type.
> * Once all entities of a type are created, fetch next type.
