Hiroshi Ikeda created HBASE-14479: ------------------------------------- Summary: Apply the Leader/Followers pattern to RpcServer's Reader Key: HBASE-14479 URL: https://issues.apache.org/jira/browse/HBASE-14479 Project: HBase Issue Type: Improvement Components: IPC/RPC, Performance Reporter: Hiroshi Ikeda Assignee: Hiroshi Ikeda Priority: Minor
{{RpcServer}} uses multiple selectors to read data for load distribution, but the distribution is just done by round-robin. It is uncertain, especially for long run, whether load is equally divided and resources are used without being wasted. Moreover, multiple selectors may cause excessive context switches which give priority to low latency (while we just add the requests to queues), and it is possible to reduce throughput of the whole server. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
