The driver waits for the subquery to finish, but it's the executor that uses the results of the subquery (for predicate codegen or evaluation). Because {{shouldBroadcast}} is set to false, the result is stored in a transient field ({{InSubqueryExec#result}}), so the result of the subquery is not serialized when the {{InSubqueryExec}} instance is sent to the executor. When wholestage codegen is enabled, the predicate codegen happens on the driver, so the subquery's result is available. When adaptive execution is enabled, {{PlanAdaptiveSubqueries}} always sets {{shouldBroadcast=true}}, so the subquery's result is available on the executor, if needed. -- 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
