System-Versioned Tables in MariaDB (via) Fascinating new feature from the SQL:2011 standard that’s getting its first working implementation in MariaDB 10.3.4. “ALTER TABLE products ADD SYSTEM VERSIONING;” causes the database to store every change made to that table—then you can run “SELECT * FROM products FOR SYSTEM_TIME AS OF TIMESTAMP @t1;” to query the data as of a specific point in time. I’ve tried all manner of horrible mechanisms for achieving this in the past, having it baked into the database itself would be fantastic.
