Hi Nicolas,

I have been following QuestDB for sometime now. I use QuestDB as an example for well-written minimal dependency Java projects.

It would be great if you could link the commits/diffs for the Kahan and Neumaier summations too in this post so we can look into the changes required for such an undertaking.

Another idea for a blog post would be tips on how to vectorize Java code. AFAIK, the JVM auto-vectorizes code or we need to use C++ code via JNI.

Thanks,
Raunak
