> Key: FLINK-22963
> URL: https://issues.apache.org/jira/browse/FLINK-22963
> Project: Flink
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 1.10.0, 1.12.0, 1.13.0
> Reporter: JasonLee
> Priority: Minor
> Labels: documentation
>
> When I studied the memory model of TaskManager, I found that there is a
> problem in the official document, which is the description of
> taskmanager.memory.task.heap.size is incorrect.
> According to the official memory model, I think the correct description
> should be that task Heap Memory size for TaskExecutors. This is the size of
> JVM heap memory reserved for tasks. If not specified, it will be derived as
> Total Flink Memory minus Framework Heap Memory, Framework Off-Heap Heap
> Memory, Task Off-Heap Memory, Managed Memory and Network Memory.
> However, in the official document, the Framework Off-Heap Heap Memory should
> be subtracted.
