Summary: 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
Fix For: 1.11.0
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)
