MariaDB TX 3.0 introduces built-in, system-versioned tables, enabling developers to easily build temporal features into applications. This eliminates the need to manually create columns, tables and triggers in order to maintain row history, freeing DBAs to simply create new tables with system versioning or alter existing tables to add it, streamlining the process significantly. Developers can query a table with standard SQL to see what data looked like at a previous point in time, such as looking at a customer’s profile history to see how preferences have changed over time.
