Data locality in data integration applications

摘要

A computer-implemented method includes identifying a logical node. The logical node is associated with one or more source stages. The computer-implemented method further includes identifying one or more file block components. The one or more file block components include a retrieval target for at least one of the one or more source stages. The computer-implemented method further includes identifying one or more physical nodes and determining, for each of the one or more physical nodes, a degree value. A corresponding computer program product and computer system are also disclosed.
