Aaron Davidson created SPARK-4183: ------------------------------------- Summary: Enable Netty-based BlockTransferService by default Key: SPARK-4183 URL: https://issues.apache.org/jira/browse/SPARK-4183 Project: Spark Issue Type: Bug Reporter: Aaron Davidson Assignee: Aaron Davidson
Spark's NettyBlockTransferService relies on Netty to achieve high performance and zero-copy IO, which is a big simplification over the manual connection management that's done in today's NioBlockTransferService. Additionally, the core functionality of the NettyBlockTransferService has been extracted out of spark core into the "network" package, with the intention of reusing this code for SPARK-3796 ([PR #3001|https://github.com/apache/spark/pull/3001/files#diff-54]). We should turn NettyBlockTransferService on by default in order to improve debuggability and stability of the network layer (which has historically been more challenging with the current BlockTransferService). -- 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
