[jira] [Updated] (SPARK-3600) RDD[Double] doesn't use primitive arrays for caching
[ https://issues.apache.org/jira/browse/SPARK-3600?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Nicholas Chammas updated SPARK-3600: Component/s: Spark Core RDD[Double] doesn't use primitive arrays for caching Key: SPARK-3600 URL: https://issues.apache.org/jira/browse/SPARK-3600 Project: Spark Issue Type: Improvement Components: Spark Core Affects Versions: 1.1.0 Reporter: Xiangrui Meng RDD's classTag is not passed in through CacheManager. So RDD[Double] uses object arrays for caching, which leads to huge overhead. However, we need to send the classTag down many levels to make it work. -- 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
