mariadb-syntax-system-versioned-tables

You can track data history in MariaDB by creating system-versioned tables using the `WITH SYSTEM VERSIONING` syntax. This automatically records row-level insertions, updates, and deletions to maintain a full audit trail of temporal data changes.

System-versioned tables are a MariaDB feature that automatically tracks all historical changes to rows over time. You need them for long-term data retention, regulatory compliance like GDPR, and precise time travel queries for auditing and debugging.

To retrieve historical data at a specific point in time in MariaDB, you use time travel queries against system-versioned tables. This allows you to query the exact state of rows when they were inserted, updated, or deleted using temporal data management.

Yes, you can model business-time periods alongside system-time history in MariaDB using bitemporal modeling. This combines application-time periods for business logic, such as contract validity, with system-time tracking for comprehensive data history.

Yes, MariaDB system versioning works for regulatory reporting and compliance by providing long-term retention of transaction history. It tracks all row-level changes with corresponding timestamps, which is essential for meeting GDPR and other regulatory requirements.

System versioning in MariaDB requires careful schema design to manage the storage overhead of historical rows. It is best suited for databases requiring long-term retention of data changes and transaction history, rather than high-performance workloads where historical data is not needed.
