> Key: FLINK-7378
> URL: https://issues.apache.org/jira/browse/FLINK-7378
> Project: Flink
> Issue Type: Sub-task
> Components: Core
> 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}} directly.
