>
> DefaultMetadataService.loadEntities() is called at the conclusion of entity
> creation and update, to load the created/updated entities which are passed to
> the EntityChangeListener's. The entities are being loaded one at time,
> because MetadataRepository does not expose a method to retrieve multiple
> entities by GUID. MetadataRepository can be enhanced to provide a
> getEntityDefinitions() entrypoint, and the implementation in
> GraphBackedMetadataRepository can batch the vertex retrievals using
> GraphHelper.getVerticesForGUIDs(). This will reduce the graph calls to
> retrieve the vertices.
