Joe Moser commented on FLINK-16428:
-----------------------------------
[~kevin.cyj], i think it might make sense to also add somewhere in the
documentation a section that could be more of a guide for this set of features.
maybe at a place like this:
[https://ci.apache.org/projects/flink/flink-docs-master/docs/deployment/memory/mem_trouble/#ioexception-insufficient-number-of-network-buffers]
i guess users might have a hard time to find and understand it.
what do you think?

> Components: Runtime / Network
> Reporter: Zhijiang
> Priority: Critical
> Fix For: 1.14.0

>
> 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)
