Here’s my DDL and query, can you build a fiddle testbed with 1M synthetic rows so I can compare performance?
My query runs slower in 25.3 than 22.3 — let’s reproduce it in fiddle with sample data.
Recreate my schema but only with the columns actually used in used in the query.
Transform this query to use CTEs for better readability.
Replace countDistinct/uniqExact with an approximate version and measure performance.
Remove unnecessary parentheses and simplify this query.
Generate test data for my tables using INSERT … SELECT FROM numbers() (e.g., 1M rows).
