HammerDB

HammerDB is the leading benchmarking and load testing software for the worlds most popular databases supporting Oracle Database, Microsoft SQL Server, IBM Db2, PostgreSQL, MySQL and MariaDB.

About This fork

This fork contains HammerDB 4.5 with additional changes for running MariaDB Xpand. In addition bin and lib contains pre-build binaries for running it on RedHat 8/Rocky8 Linux only. It is recommend to use Maxscale in the front of Xpand cluster.

./mariadb_repo_setup --mariadb-server-version=mariadb-10.7

dnf install -y MariaDB-client MariaDB-shared

Example TCL script for MariaDB Xpand

As MariaDB Xpand is MariaDB compatible we decided to leave all parameters names start with maria.

Evaluating the results

Please note that HammerDB uses a derived from TPC-C version TPROC-C, therefore you could only compare results within the same benchmark (HammerDB). See for example discussion here.
