Thanks a lot for your work Francis and +1 for Stamatis to be the next PMC chair ~ ~
Calcite is a great project and it offers as a strong SQL engine to help users to build data systems. My group uses Calcite to accelerate SQLs from multiple data engines by heuristic based, cost based and materialization based optimization. As a developer, I really benefit a lot from Calcite and the help from this great community. Calcite is not well known ? Yes, it might be less heard by the end users (who focus on data analysis), but most of data engine developers (AFAIK) know that Calcite is always a good choice when they want to build a strong SQL engine for their data systems. This is the charm of Calcite. Finally, I agree with Muhammad Gelbana to strenghten documentation for Calcite.
