------------------------------------
Assignee: Xu Hao
> Rename misleading variable names
> --------------------------------
>
> Key: FLINK-36342
> URL: https://issues.apache.org/jira/browse/FLINK-36342
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing
> Reporter: Xu Hao

>
> The variable named targetTotalBufferSize appears in class
> BufferDebloatConfiguration and some other classes has been incorrectly named.
> Based on the context and the origin of this variable, it is clearly a
> *Duration* type variable that is read from configuration(the key is
> *taskmanager.network.memory.buffer-debloat.target* and default value is 1s).
> So a more suitable name might be targetTotalTime.
> This variable is used to calculate buffer size(see
> BufferDebloater#recalculateBufferSize), the specific code is as follows:
> long desiredTotalBufferSizeInBytes = (currentThroughput *
> targetTotalBufferSize) / MILLIS_IN_SECOND;
> If the variable name is not corrected, maintainers might find it is quite
> difficult to understand why the current throughput is multiplied by the
> target buffer size to calculate the total buffer size.
