Hi Community, I have a question about the taskmanager.memory.preallocate config in the doc https://ci.apache.org/projects/flink/flink-docs-release-1.8/ops/config.html#taskmanager-memory-preallocate <https://ci.apache.org/projects/flink/flink-docs-release-1.8/ops/config.html#taskmanager-memory-preallocate>
We have large memory box so as it suggested we should use off heap memory for flink managed memory. And the doc then suggests to set taskmanager.memory.preallocate to true. However, "For streaming setups is is highly recommended to set this value to false as the core state backends currently do not use the managed memory." Our flink set up is mainly for streaming jobs so I think the above applies to our case. So should I use off-heap with “preallocate" setting to false? What would be the impact with these configs? Thank you very much! Best, Ethan
