HammerDB

JUNE 27, 2022

HammerDB is a software application for database benchmarking. It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. The HammerDB name.

Shift Left is a testing approach where testing begins right from the software development phase. Besides, with the growth of CI and CD, it makes more sense to test out the features or any aspects of the software rather than waiting for the final stages. You can also gain frontend performance insights much before the software goes live.
