Package org.apache.flink.runtime.util.config.memory

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.
