Abstract:
An improved system and method for loading records into a partitioned database table is provided. A translation of records may be generated from a set of source partitions to a set of target partitions by generating a bipartite graph, determining a maximal matching using dynamic programming for a chain of nodes remaining in the bipartite graph after removing singleton edges, and generating a maximal matching after adding back the singleton edges for translation of records from the set of source partitions to the set of target partitions. The partition translation may be executed by traversing from top to bottom the set of source partitions and the set of target partitions in record key order to generate an optimal sequence of operations to transfer the records from the set of source partitions to the set of target partitions.
