HammerDB
What it is
HammerDB is a database benchmarking application for running workloads across SQL Server, Db2, Oracle, PostgreSQL, MariaDB, MySQL, and VillageSQL. It supports graphical, command-line, web, and automation interfaces and is available for on-premise use. The free HammerDB plan costs nothing and is released under the GNU General Public License Version 3. Version 6.0 adds CI and pipeline capabilities for MariaDB, MySQL, and PostgreSQL, including schema sizing, workload execution, and result capture. It also includes I/O metrics such as IOPS and MB/s, plus Active Session History viewers for MySQL and MariaDB. Timing profiles use reservoir sampling and extended percentile reporting to compare response-time distributions. Users can upload benchmark artifacts containing workload results, database versions, metrics, and system metadata for publication or review. The web service can run as an SCGI application behind a web server or automation gateway. Documentation describes CI and pipeline automation as an advanced capability for users automating database builds and benchmark workflows. Such workflows may require a compiler, database build dependencies, client and runtime libraries, and operating-system tools for the selected database and workload.
