> Key: FLINK-29299
> URL: https://issues.apache.org/jira/browse/FLINK-29299
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Network
> Affects Versions: 1.16.0
> Reporter: Yingjie Cao
> Assignee: Yingjie Cao
> Priority: Critical
> Fix For: 1.16.0

>
> After FLINK-28663, one intermediate dataset can be consumed by multiple
> consumers, there is a case where one vertex can consume one intermediate
> dataset multiple times. However, currently in fine-grained resource mode,
> when computing the required network buffer size, the intermediate dataset is
> used as key to record the size of network buffer per input gate, which means
> it may allocate less network buffers than needed if two input gate of the
> same vertex consumes the same intermediate dataset.
