The subject technology executes a change on an existing micro-partition of a table of a database, the executing of the change comprising generating a new micro-partition that embodies the change. The subject technology receives a request for a delta for the table between a first timestamp and a second timestamp. The subject technology queries at least one change tracking column to determine the delta between the first timestamp and the second timestamp, the delta including information indicating at least one database operation that was performed to at least one row of a set of rows of the table, without including information as to intermediate changes made to at least one row of the set of rows of the table between the first timestamp and the second timestamp, that facilitates a reduction in storage of historical versions of the set of rows of the table.
