This is especially in the areas of COUNT bugs and > null behaviors. > To increase test coverage and robustness in this area, we want to write a > subquery generator that writes variations of subqueries, producing SQL tests > that also run against Postgres (from my work in SPARK-46179). -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
