Important: there is no guarantee that there will be no more than one UpstreamEntry with given key,
UpstreamEntry should be thought rather as a container saving all data from upstream, but omitting uniqueness
constraint. This constraint is omitted to allow upstream data transformers in DatasetBuilder
replicating
entries. For example it can be useful for bootstrapping.build
