zhijiang created FLINK-7406: ------------------------------- Summary: Implement Netty receiver incoming pipeline for credit-based Key: FLINK-7406 URL: https://issues.apache.org/jira/browse/FLINK-7406 Project: Flink Issue Type: Sub-task Components: Network Reporter: zhijiang Assignee: zhijiang Fix For: 1.4.0
This is a part of work for credit-based network flow control. Currently {{PartitionRequestClientHandler}} receives and reads {{BufferResponse}} from producer. It will request buffer from {{BufferPool}} for holding the message. If not got, the message is staged temporarily and {{autoread}} for channel is set false. For credit-based mode, {{PartitionRequestClientHandler}} can always get buffer from {{RemoteInputChannel}} for reading messages from producer. The related works are: * Add the backlog of producer in {{BufferResponse}} message structure * {{PartitionRequestClientHandler}} requests buffer from {{RemoteInputChannel}} directly * {{PartitionRequestClientHandler}} updates backlog for {{RemoteInputChannel}}, and it may trigger requests of floating buffers from {{BufferPool}} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
