Hello,
We've been using Calcite at Picnic <https://picnic.app/nl/> for quite some time now and it's enabled us to do many great things :). We published a tech blog post about our motivation and experience of using Calcite for our use-cases here <https://blog.picnic.nl/enabling-rapid-business-use-case-iteration-with-apache-calcite-6ee9b13287f8> and wanted to share it with the community as well. Any feedback is definitely welcome!
