@carltal It depends on how the SQL query is translated. The planner makes some effort to translate `coalesce` in a low-impact way. Ideally for a situation like this, it will be translated to a post-aggregator, where it's applied just once on the result of the aggregation. You can check `EXPLAIN PLAN FOR` to see how the query is being translated. -- This is an automated message from the Apache Git Service.
