[jira] [Created] (FLINK-15143) Create document for FLIP-49 TM memory model and configuration guide

Xintong Song created FLINK-15143:
------------------------------------

             Summary: Create document for FLIP-49 TM memory model and configuration guide
                 Key: FLINK-15143
                 URL: https://issues.apache.org/jira/browse/FLINK-15143
             Project: Flink
          Issue Type: Task
          Components: Documentation
    Affects Versions: 1.10.0
            Reporter: Xintong Song
             Fix For: 1.10.0


In release 1.10, with FLIP-49, we introduced significant changes to the TaskExecutor memory model and it's related configuration options / logics.

It is very important that we clearly state the changes and potential effects, and guide our users to tune their clusters with the new configuration for both new setups and migrations of previous setups. And we should do that for both documentation and the release note.
