Re: CockroachDB optimizer


Thanks for sharing this Michael!

I had a look on their blog post but I didn't notice something really novel.
It gives me the impression that they re-implemented a Volcano-style
optimizer like the one of Calcite.

Out of curiosity, are they using Calcite, or they really built everything
from scratch?

Best,
Stamatis
