Xintong Song commented on FLINK-22963:
--------------------------------------
[~jasonlee1017], thanks for reporting this issue and volunteering to fix it.
I've assigned you to the ticket.
According to the [release update
policy|https://flink.apache.org/downloads.html#update-policy-for-old-releases],
the community provides bugfixes only for the latest release and the one before
it. That means this should be fixed for 1.12, 1.13 and of course the upcoming
1.14 releases.
Usually, the contributors only need to open PRs against the master branch and
the committers will port the changes to the old release branches if needed. For
this ticket, we probably need an additional PR against 1.12, because we have
switched our document framework from Ruby to Hugo since1.13.

> Project: Flink
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 1.14.0, 1.13.1, 1.12.4
> Reporter: JasonLee
> Assignee: JasonLee
> Priority: Major
> Labels: documentation, starter

> 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.
