Yingjie Cao commented on FLINK-16428: ------------------------------------- Though the PR is ready, I guess we do not have enough time to merge it into 1.13, moving the fix version to 1.14. > Fine-grained network buffer management for backpressure > ------------------------------------------------------- > > Key: FLINK-16428 > URL: https://issues.apache.org/jira/browse/FLINK-16428 > Project: Flink > Issue Type: Improvement > Components: Runtime / Network > Reporter: Zhijiang > Priority: Critical > Fix For: 1.13.0 > > > It is an umbrella ticket for tracing the progress of this improvement. > This is the second ingredient to solve the “checkpoints under backpressure” > problem (together with unaligned checkpoints). It consists of two steps: > * See if we can use less network memory in general for streaming jobs (with > potentially different distribution of floating buffers in the input side) > * Under backpressure, reduce network memory to have less in-flight data > (needs specification of algorithm and experiments) -- This message was sent by Atlassian Jira (v8.3.4#803005)
