Abstract
Systems, methods, and devices for tracking changes to database data. A method includes determining a change to be executed on a micro-partition of a table of a database and executing the change on the table by generating a new micro-partition that embodies the change. The method includes updating a table history that includes a log of changes made to the table, wherein each change in the log of changes includes a timestamp, and wherein updating the table history includes inserting the change into the log of changes.
