摘要
Approaches for referential sampling of disparate datasets. An execution mode and a sampling mode are determined for each entity in a plurality of disparate datasets. A directed acyclic graph (DAG) for each entity in the plurality of disparate datasets is created. The directed acyclic graph (DAG) is topologically sorted to produce a topologically sorted directed acyclic graph (DAG). One or more sampled datasets are retrieved from the plurality of disparate datasets using the topologically sorted directed acyclic graph (DAG). Advantageously, the one or more sampled datasets are a consistent sample that honors all referential constraints in the plurality of disparate datasets.
