I really appreciate the fact that many people jumped in and helped to
shoot this down and restabilise CI. Many thanks from my side as well
to everyone involved!

Best,
Stamatis

Thank you to everyone who worked on this - Stamatis, Benchao, Hongyu, Jiajun, 
and maybe some I’ve missed. It sounded like a very tricky bug to diagnose. (And 
it wasn’t even a Calcite bug in the end!) A solid, reliable CI system is the 
foundation of high-quality software.

Gian, The cause seems to have been a subtle bug in Druid’s query cache. If you 
would like us to log a bug against Druid, let us know.

An update on this, it has been solved in CALCITE-6123 by Stamatis, the
Druid test is supposed to be stable now, thanks Stamatis for fixing
this and also thanks everyone who helped on this.
