[jira] [Updated] (SPARK-3376) Memory-based shuffle strategy to
reduce overhead of disk I/O
[ https://issues.apache.org/jira/browse/SPARK-3376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
uncleGen updated SPARK-3376:
----------------------------
Description:
I think a memory-based shuffle can reduce some overhead of disk I/O. I just want to know is there any plan to do something about it. Or any suggestion about it. Base on the work (SPARK-2044), it is feasible to have several implementations of shuffle.
