JiangHua Zhu created HDFS-16134: ----------------------------------- Summary: Optimize RPC throughput Key: HDFS-16134 URL: https://issues.apache.org/jira/browse/HDFS-16134 Project: Hadoop HDFS Issue Type: Improvement Reporter: JiangHua Zhu
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-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
