> This will only impact queries where every GROUP BY expression is constant. Any of those queries that don't already compute count(1)/count(*) will be slower ~0.9ns/row (this is from a microbench with 50M rows) but we get correctness on the corner case. Is there some way to fix this issue rather than adding a new filter (which has a per row cost)? For example, can we add a flag to the aggregate stream? -- This is an automated message from the Apache Git Service.
