Apache Spark reassigned SPARK-31199:
------------------------------------
Assignee: Apache Spark
> Separate connection timeout and idle timeout for netty
> ------------------------------------------------------
>
> Key: SPARK-31199
> URL: https://issues.apache.org/jira/browse/SPARK-31199
> Project: Spark
> Issue Type: Improvement
> Components: Shuffle
> Affects Versions: 3.1.0
> Reporter: runnings
> Assignee: Apache Spark
> Priority: Major
>
> io.connectionTimeout only used for connection timeout for connection setup
> while io.idleTimeout is used to control how long to kill the connection if it
> seems to be idle([https://github.com/apache/spark/pull/5584])
>
> These 2 timeouts could be quite different. connectiontimeout could be short
> to help fast fail the connection related problem when meet some high
> load/unstable nodes. While idle timeout may be related to business function
> performance which is more complicated.
