----------------------------------
Summary: Get rid of numberOfRequestedOverdraftMemorySegments in
LocalBufferPool
Key: FLINK-31764
URL: https://issues.apache.org/jira/browse/FLINK-31764
Project: Flink
Issue Type: Improvement
Components: Runtime / Network
Affects Versions: 1.18.0
Reporter: Weijie Guo
Assignee: Weijie Guo
We can changes the definition of overdraft buffer from static to dynamic:
* When _numberOfRequestedMemorySegments <= poolSize,_ all buffers are ordinary
buffer
* When _numberOfRequestedMemorySegments > poolSize,_ the `{_}ordinary buffer
size = poolSize`{_}, and `{_}the overdraft buffer size =
numberOfRequestedMemorySegments - poolSize`{_}
This allows us to remove {{{}numberOfRequestedOverdraftMemorySegments{}}},
which helps us simplify logic and maintain consistency.
