public class TaskExecutorFlinkMemory
extends Object
implements FlinkMemory

Flink internal memory components of Task Executor.

A TaskExecutor's internal Flink memory consists of the following components.

• Framework Heap Memory
• Framework Off-Heap Memory
• Task Heap Memory
• Task Off-Heap Memory
• Network Memory
• Managed Memory

The relationships of TaskExecutor Flink memory components are shown below.
