The following SQL cannot perform partition pruning {code:java} SELECT * FROM parquet_part WHERE id_type in (SELECT max(id_type) from parquet_part){code} As can be seen from the execution plan below, the partition pruning of left cannot be performed after the subquery of in is converted into join !image-2023-08-03-17-17-34-858.png! The current issue proposes to optimize insubquery. Only when the value of in is greater than a threshold, insubquery will be converted into Join -- 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
