Nico Kruber commented on FLINK-10742:
-------------------------------------
[~gaoyunhaii] thanks for taking care of this - I didn't have plans to do it
myself but wanted to drop it here since it was always planned but never done
and this would finally conclude FLINK-7315.
Looking forward to the design doc. At the moment, we'd have to go two different
paths for credit vs. non-credit flow control though. Not sure if we should
remove the old code paths first to make things simpler. I think for an initial
implementation you could start assuming that credits are always used and we'll
decide later.
> Let Netty use Flink's buffers directly in credit-based mode

> For credit-based flow control, we always have buffers available for data that
> is sent to use. We could thus use them directly and not copy the network
> stream into Netty buffers first and then into our buffers.
