org.apache.flink.runtime.util.config.memory.jobmanager.JobManagerFlinkMemory

All Implemented Interfaces:

Serializable, FlinkMemory

public class JobManagerFlinkMemory
extends Object
implements FlinkMemory

Flink internal memory components of Job Manager.

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

• JVM Heap Memory
• Off-Heap Memory (also JVM Direct Memory)

The relationships of Job Manager Flink memory components are shown below.

               ┌ ─ ─  Total Flink Memory - ─ ─ ┐
                 ┌───────────────────────────┐
               | │       JVM Heap Memory     │ |
                 └───────────────────────────┘
               │ ┌───────────────────────────┐ │
                 |    Off-heap Heap Memory   │   -─ JVM Direct Memory
