1. A computer-implemented method, comprising:
detecting that a sequence of data changes was made to data values of a database table, wherein the sequence of data changes is indexed in a data change index based on pseudorandom numbers;
determining a first invocation number and a second invocation number greater than the first invocation number;
generating a sequence of pseudorandom numbers for all invocation numbers ranging between the first invocation number and the second invocation number, wherein the sequence of pseudorandom numbers begins with a first pseudorandom number generated based on a seed value assigned to the database table and the first invocation number, and wherein the sequence of pseudorandom numbers ends with a second pseudorandom number generated based on the seed value and the second invocation number; and
retrieving, via entries of the data change index that are accessed using the sequence of pseudorandom numbers, the sequence of data changes made to the data values of the database table.
