JiangHua Zhu commented on HDFS-16134: ------------------------------------- [~elgoiri], [~ayushtkn], [~hexiaoqiao], do you have any different ideas? Welcome to communicate. > Optimize RPC throughput > ----------------------- > > Key: HDFS-16134 > URL: https://issues.apache.org/jira/browse/HDFS-16134 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: JiangHua Zhu > Priority: Major > > Now RPC has the following phenomena: > 1. Each RPC has 1 Responder, which is used to return the result, but many > client requests are directly returned after the handler is processed; > 2. Call#Connection#responseQueue uses synchronous control every time it is > used; > These phenomena will hinder the performance of RPC, we can try to make some > changes. > 1. Set multiple responders for each RPC, and the user returns the result; > 2. After the Handler processing is completed, add the results that need to be > returned to a queue, and the Responder will process the queue data; > 3. Add an identifier similar to sequenceId to ensure the order of return; -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
