Abstract
A method, system, and computer system for performing an operation with respect to a target table are disclosed. The method includes performing first and second jobs, and obtaining other resulting files based at least in part on a second set of unmatched rows among the target table and the source table that results from the first set of unmatched rows having been processed in the second job, and obtaining a resulting table based on (i) second job resulting file(s), and (ii) other resulting files. Performing the first job includes determining a set of matching target table files and storing target table information indicating for each of the set of matching target table files, a particular set of rows having matching rows. Performing the second job includes performing a first matching action based on matched rows and a second matching action based on a subset of unmatched rows.
