should we add a `Preconditions.checkArgument(numRequiredBuffers > 0)`?
> Create a fix size (non rebalancing) buffer pool type for the floating buffers

> Project: Flink
> Issue Type: Sub-task

> Reporter: zhijiang
> Assignee: zhijiang
> Fix For: 1.4.0
>
>
> Currently the number of network buffers in {{LocalBufferPool}} for
> {{SingleInputGate}} is limited by {{a * <number of channels> + b}}, where a
> is the number of exclusive buffers for each channel and b is the number of
> floating buffers shared by all channels.
> Considering the credit-based flow control feature, we want to create a fix
> size buffer pool used to manage the floating buffers for {{SingleInputGate}}.
> And the exclusive buffers are assigned to {{InputChannel}}s directly.
