> 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)
