From the previous post we now have source and binary copies of HammerDB for modification and test. The next step is to see if there is an Issue already created for the database we want to add or whether we should create one. You can now begin modifying the source to add your database. <? . <mariadb>

cloud based usage led to the development of a HammerDB HTTP based web service interface with output data stored in a SQLite database repository. ws_port defines on which port to start the HTTP service, whilst sqlite_db sets the location of the SQLite repository database.

Note that the main developer of HammerDB is Intel employee (#IAMINTEL) however HammerDB is a personal open source project and HammerDB has no optimization whatsoever for a database running on any particular architecture. So to test I took a system with Skylake CPUs and all storage on a P4800X SSD. In the recent MySQL 8.0.16

HammerDB already has 2 interfaces with which to interface with the commands to build and test databases using the GUI interface or CLI. The following test script shows how this interaction can be done also including deliberate errors to demonstrate error handling. From HammerDB version 3.2 hammerdbws HammerDB Web Service v3.2

I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R. We had specializations in hardware, operating systems, databases, graphics, etc. It was the first database sizing guide Sun had ever produced.

The TPC publishes an official Docker image on Docker Hub to enable the rapid deployment and testing of databases with HammerDB. This image includes example scripts to build schemas and test your databases with a single command. Our Linux test system is running a MariaDB 10.10 Database Configuration.

If you are not already familiar with the programming languages that HammerDB uses, then this earlier post serves as an ideal introduction to what makes up the highest performing GIL free database benchmarking application. The build has been tested on x64 Red Hat 8.X The build has been tested on x64 Windows 10 and 11.

Python is a popular programming language, especially for beginners, and consequently we see it occurring in places where it just shouldn’t be used, such as database benchmarking. We use stored procedures because, as the introductory post shows, using single SQL statements turns our database benchmark into a network test).

However if you have downloaded the source code and are looking to add features or make modifications such as adding new databases you may be wondering once you have the source code where to start. However HammerDB will not be able to connect to a database yet and the librarycheck command included with the CLI gives an indication why.

One of the most important concepts in analysing database performance is that of understanding scalability. The way we measure this is through a ‘performance profile’ This simply means that we run a series of tests incrementally increasing the system load until we find the peak performance. and MySQL 8.0.25 and MySQL 8.0.25

This post complements the previous best practice guides this time with the focus on MySQL and MariaDB and achieving top levels of performance with the HammerDB MySQL TPC-C test. Similarly for this guide MySQL can be swapped for a mySQL based databases such as MariaDB. SELECT DISTINCT c from sbtest where id between ?

This post gives a HOWTO guide on system configuration for achieving top levels of performance with the HammerDB PostgreSQL TPC-C test. D isabling all C-states or Idle states is likely to reduce overall performance by reducing the available turbo frequency. It is your test so you can set the options as you see fit.
