枚举 GlobalDataExchangeMode

java.lang.Object

java.lang.Enum<GlobalDataExchangeMode>

org.apache.flink.streaming.api.graph.GlobalDataExchangeMode

所有已实现的接口:

Serializable, Comparable<GlobalDataExchangeMode>

public enum GlobalDataExchangeMode
extends Enum<GlobalDataExchangeMode>

This mode decides the default ResultPartitionType of job edges. Note that this only affects job edges which are ShuffleMode.UNDEFINED.

枚举常量概要

枚举常量和说明
ALL_EDGES_BLOCKING Set all job edges to be ResultPartitionType.BLOCKING.
ALL_EDGES_PIPELINED Set all job edges ResultPartitionType.PIPELINED_BOUNDED.
ALL_EDGES_PIPELINED_APPROXIMATE Set all job edges ResultPartitionType.PIPELINED_APPROXIMATE.
FORWARD_EDGES_PIPELINED Set job edges with ForwardPartitioner to be ResultPartitionType.PIPELINED_BOUNDED and other edges to be ResultPartitionType.BLOCKING.
POINTWISE_EDGES_PIPELINED Set job edges with ForwardPartitioner or RescalePartitioner to be ResultPartitionType.PIPELINED_BOUNDED and other edges to be ResultPartitionType.BLOCKING.

ALL_EDGES_BLOCKING

public static final GlobalDataExchangeMode ALL_EDGES_BLOCKING

Set all job edges to be ResultPartitionType.BLOCKING.

FORWARD_EDGES_PIPELINED

public static final GlobalDataExchangeMode FORWARD_EDGES_PIPELINED

方法详细资料

values

public static GlobalDataExchangeMode[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (GlobalDataExchangeMode c : GlobalDataExchangeMode.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static GlobalDataExchangeMode valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
