Aaron Davidson commented on SPARK-5124: --------------------------------------- I tend to prefer having explicit message.reply() semantics over Akka's weird ask. This is how the Transport layer implements RPCs, for instance: https://github.com/apache/spark/blob/master/network/common/src/main/java/org/apache/spark/network/server/RpcHandler.java#L26 I might even supplement message with a reply with failure method, so exceptions can be relayed. I have not found this mechanism to be a bottleneck at many thousands of requests per second. > Standardize internal RPC interface > ---------------------------------- > > Key: SPARK-5124 > URL: https://issues.apache.org/jira/browse/SPARK-5124 > Project: Spark > Issue Type: Sub-task > Components: Spark Core > Reporter: Reynold Xin > Assignee: Shixiong Zhu > Attachments: Pluggable RPC - draft 1.pdf, Pluggable RPC - draft 2.pdf > > > In Spark we use Akka as the RPC layer. It would be great if we can > standardize the internal RPC interface to facilitate testing. This will also > provide the foundation to try other RPC implementations in the future. -- 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
