Distributed SQL queries are cool and accessible to people but I feel like projects that apply relational languages to event data don't make much sense. If I have click stream data then I'm more interested in knowing what users are doing after they performed action "A", "B" & "C" than rolling up how many users performed a single action "A". SQL falls flat on its face for this type of analysis.
Also, the name also threw me off. I thought it was "Citrus" and not "Citus".
