摘要: In one general aspect, a computer system can include instructions stored on a non-transitory computer-readable storage medium. The computer system can include a logging table generator configured to generate a logging table corresponding with an original table targeted for an upgrade, and a control table generator configured to generate a control table configured to store a version identifier for changes logged in the logging table. The computer system can include a change recorder configured to receive an indicator of a change to a record of the original table during execution of at least a portion of the upgrade of the original table, and a key recorder configured to store in the logging table a primary key identifying the record of the original table and the version identifier stored in the control table.
