Three configuration sources are now ranked by priority: an external db_config_file (lowest), an inline config block in the user properties (middle), and a command-line override (highest, always wins). Whichever source wins, TAF generates a temporary config file, uses it to start the database, and archives it with results, improving reproducibility. A follow-up post will cover TAF's auto-generated, fully resolved user properties file produced on every run. TAF now supports MariaDB, MySQL, and PostgreSQL, and the post closes with a Hetzner hardware sponsorship acknowledgment and an open call for other database vendors to adopt TAF. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How does TAF decide which database configuration file to use when multiple sources are defined? TAF uses a three-tier priority system: an external file referenced via taf.db_config_file has the lowest priority, an inline database configuration block embedded in the user properties file overrides it, and a command-line --db-config-file argument has the highest priority and always wins. Whichever source wins, TAF generates a temporary config file, uses it to start the database, and archives it with the results. _Developers managing test configs across environments can follow database tooling changes like this on daily.dev._ ### Which databases does the MariaDB TAF testing framework support? TAF supports MariaDB, MySQL, and PostgreSQL, enabling full multi-database workload testing and reproducible performance runs across all three. It was engineered and validated on Hetzner hardware, including an Intel i5-13500 host and an AMD EPYC 9454 host, to expose real performance behavior across these database engines. _Teams comparing database performance tooling across MariaDB, MySQL, and PostgreSQL can track updates like this on daily.dev._ ## Similar posts on daily.dev -
