Mridul Muralidharan commented on SPARK-3019: -------------------------------------------- Just went over the proposal in some detail. [~rxin] did you take a look at the proposal in SPARK-1476 ? The ManagedBuffer detailed in this document does not satisfy most of the interface or functional requirements in 1476 - which would require us to redesign this interface when we need to support larger than 2 GB for blocks in spark : unless I missed something. > Pluggable block transfer (data plane communication) interface > ------------------------------------------------------------- > > Key: SPARK-3019 > URL: https://issues.apache.org/jira/browse/SPARK-3019 > Project: Spark > Issue Type: Improvement > Components: Shuffle, Spark Core > Reporter: Reynold Xin > Assignee: Reynold Xin > Attachments: PluggableBlockTransferServiceProposalforSpark - draft > 1.pdf > > > The attached design doc proposes a standard interface for block transferring, > which will make future engineering of this functionality easier, allowing the > Spark community to provide alternative implementations. > Block transferring is a critical function in Spark. All of the following > depend on it: > * shuffle > * torrent broadcast > * block replication in BlockManager > * remote block reads for tasks scheduled without locality -- 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
