1. A method for managing lineage information in a computing system, the method including:
receiving, over an input device or port, an identification of a directed graph that includes one or more data transformation nodes that represent computations that transform data elements and one or more data nodes that represent data elements, and includes directed links that represent respective lineage relationships between a computation and a data element to be received or produced by the computation during execution of the computation; and computing, using at least one processor, summary information based on paths in the directed graph, and storing the summary information in one or more summary objects, the computing including
receiving designation of interest for a plurality of the nodes of the directed graph; andgenerating one or more summary objects for remaining nodes not included in the plurality of nodes of interest, a first summary object of the one or more summary objects including summary information based on a first path between a first node of interest and a second node of interest that does include one or more of the remaining nodes and does not include any nodes of interest other than the first and second nodes. |
