> Key: FLINK-32549
> URL: https://issues.apache.org/jira/browse/FLINK-32549
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Network
> Affects Versions: 1.18.0
> Reporter: Yuxin Tan
> Assignee: Yuxin Tan
> Priority: Major
> Labels: pull-request-available
>
> Currently, the accumulator is responsible for requesting all buffers, leading
> to an inaccurate number of requested buffers for each tier.
> To address this issue, buffer ownership must be transferred from the
> accumulator to the tiers when writing them, which will enable the memory
> manager to maintain a correct number of requested buffers for different
> owners.
