Hi @NicoK , I am interested in this issue and I like the way of asserting
hold lock in this PR.
It is really necessary to manage network buffers by framework, because it
is difficult to set the exact number of buffers by users. And our current
simple solution is to expand the `ResourceProfile` by adding the total number
of input and output edges for `Execution`. Then the `ResourceManager` would
calculate the buffer amounts based on that and overwrite the parameter value to
`TaskManager` configuration.
From @StephanEwen mentioned before, I know a little for this issue. Would
you share some detail designs for plans for it if have, then I can learn and
track the progress in time. Thank you !
