---------------------------------
Summary: Tiered storage memory manager supports ownership transfer
for buffers
Key: FLINK-32549
URL: https://issues.apache.org/jira/browse/FLINK-32549
Project: Flink
Issue Type: Sub-task
Components: Runtime / Network
Affects Versions: 1.18.0
Reporter: Yuxin Tan
Assignee: Yuxin Tan
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.
