THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

Off-heap memory for network buffers.
(taskmanager.memory.networkshuffle.[min/max/fraction]) or (taskmanager.network.memory.[min/max/fraction])
...
Deprecated configuration keys are as follows:
| Deprecated Key | As Fallback of New Key | Notes |
|---|---|---|
| taskmanager.heap.size | taskmanager.memory.total-flink.size | |
| taskmanager.heap.mb | taskmanager.memory.total-flink.size | |
| taskmanager.memory.size | taskmamager.memory.managed.size | |
| taskmanager.memory.fraction | taskmanager.memory.managed.fraction | |
| taskmanager.memory.off-heap | taskmanager.memory.managed.offheap-fraction | `taskmanager.memory.managed.offheap-fraction` is set to `1.0`, if it is not explicitly configured by the user and `taskmanager.memory.off-heap` is `true`. |
| taskmanager.memory.preallocate | N/A | `taskmanager.memory.preallocate` will be ignored, because we no-longer support pre-allocation of managed memory. |
| taskmanager.network.memory.[min/max/fraction] | taskmanager.memory. |
| shuffle.[min/max/fraction] |
Test Plan
- We need to update existing and add new integration tests dedicated to validate the new memory configuration behaviors.
- It is also expected that other regular integration and end-to-end tests should fail if this is broken.
