HammerDB

JULY 5, 2022

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. What programming languages does HammerDB use and why does it matter? Surely any language will do? Background and Concepts.

FEBRUARY 25, 2021

HammerDB is a load testing and benchmarking application for relational databases. However, it is crucial that the benchmarking application does not have inherent bottlenecks that artificially limits the scalability of the database. This is why the choice of programming language is so important from the outset.

The idea behind this is to speed up cluster resources such as garbage collection, reduce image transfer over the network, and accelerate the application launch.
