The Importance of Benchmarking
Benchmarking is a crucial tool in the database engineering field, allowing professionals to explore the limits of their systems, make data-driven decisions, and compare different situations. It serves as a stress test to push systems to their limits and identify areas for improvement. Additionally, benchmarking helps in regression testing, ensuring that system performance remains consistent or improves over time. Moreover, it aids in making critical decisions during urgent situations, such as choosing between different platform options. While benchmarking can also be used for marketing purposes, other goals like stress testing, decision-making, and regression testing are regarded as more important.
