Shixiong Zhu created SPARK-16002: ------------------------------------ Summary: Sleep when no new data arrives to avoid 100% CPU usage Key: SPARK-16002 URL: https://issues.apache.org/jira/browse/SPARK-16002 Project: Spark Issue Type: Improvement Components: SQL Reporter: Shixiong Zhu Assignee: Shixiong Zhu
Right now if the trigger is ProcessTrigger(0), StreamExecution will keep polling new data even if there is no data. Then the CPU usage will be 100%. We should add a minimum polling delay when no new data arrives. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
