Interface FlinkMemoryUtils<FM extends FlinkMemory>

Type Parameters:

FM - the Flink memory components

All Known Implementing Classes:

JobManagerFlinkMemoryUtils, TaskExecutorFlinkMemoryUtils

public interface FlinkMemoryUtils<FM extends FlinkMemory>

Utility to derive the FlinkMemory components.

The FlinkMemory represents memory components which constitute the Total Flink Memory. The Flink memory components can be derived from either its total size or a subset of configured required fine-grained components. See implementations for details about the concrete fine-grained components.
