--------------------------------
Summary: The description of taskmanager.memory.task.heap.size in
the official document is incorrect
Key: FLINK-22963
URL: https://issues.apache.org/jira/browse/FLINK-22963
Project: Flink
Issue Type: Improvement
Components: Documentation
Affects Versions: 1.13.0, 1.12.0, 1.10.0
Reporter: JasonLee
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.
