> The ResourceManager requires some way to tell whether it has received all partitions for a given dataset; to ensure that a) no incomplete datasets are shows to the user [as completed] and b) to initiate a timeout-based cleanup of other partitions.
> Conversely, since the RM only has access to what the TaskExecutor sends, this information must also be accessible to the TE.
> A good candidate for placing this seems to be the {{ResultPartitionDeploymentDescriptor}} or {{PartitionDescriptor}}, as these already contain the DataSetID.
