zhijiang updated FLINK-7468: ---------------------------- Summary: Implement sender backlog logic for credit-based (was: Implement Netty sender backlog logic for credit-based) > Implement sender backlog logic for credit-based > ----------------------------------------------- > > Key: FLINK-7468 > URL: https://issues.apache.org/jira/browse/FLINK-7468 > 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. > Receivers should know how many buffers are available on the sender side (the > backlog). The receivers use this information to decide how to distribute > floating buffers. > The {{ResultSubpartition}} maintains the backlog which only indicates the > number of buffers in this subpartition, not including the number of events. > The backlog is increased for adding buffer to this subpartition, and > decreased for polling buffer from it. > The backlog is attached in {{BufferResponse}} by sender as an absolute value > after the buffer being transferred. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
