Using SIMD to aggregate billions of values per second
QuestDB co-founder and CTO here - happy to share questdb, a performance-driven open-source time-series database that uses SQL.<p>High performance databases have a reputation of being inaccessible. They are expensive, closed-source, and require 
complex proprietary languages.<p>We have made our code available under Apache 2.0. Under this new release, QuestDB leverages SIMD instructions, vectorizations and parallel execution to achieve performance figures at the top of the high-performance databases. Results are shown in our blog post.<p>I sincerely hope that you will find this helpful, and that this will unlock new possibilities! In the meantime, we will carry on working on QuestDB, adding more features, and taking this speed to more query types. Feel free to join us on slack or Github if you want to participate.
