How do we know what our database is actually capable of? We test it. A lot. Here's a summary of some of the tests and benchmarks we run regularly to ensure CockroachDB is performant even at global scale.

What does a Test Engineer do? The Test Engineering team (TestEng) is a new and exciting team embedded within Engineering. We are accomplished engineers on a quest for higher quality. Collectively, we have built complex and impressive software systems at startups and big tech, written test frameworks and program analysis tools; and even applied formal verification and automated reasoning. We have done all of those things and more while obsessing about correctness and performance, yet never quite achieving nirvana.
