>
> *Background*
> The new Migration Import implementation allows for importing large zip files.
> These imports can potentially run for long time. If the server shuts down
> while an import is in progress, there needs to be a mechanism so that the
> import resumes from the last imported entity.
> *Solution*
> * Implement _DataMigrationStatusService_ this will maintain a special vertex
> one of whose property will be the last successfully imported status.
> * Update this vertex on each successfully recorded import.
> * At the start of _ZipFileBaseMigration_ check for existence of this vertex.
> If it exists and has a valid position, use this to set the _startPosition_ in
> the _AtlasImportRequest_.
