Enum GlobalDataExchangeMode

java.lang.Object

java.lang.Enum<GlobalDataExchangeMode>

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

All Implemented Interfaces:

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.

Enum Constant Detail

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

Set job edges with ForwardPartitioner to be ResultPartitionType.PIPELINED_BOUNDED and other edges to be ResultPartitionType.BLOCKING.

POINTWISE_EDGES_PIPELINED

public static final GlobalDataExchangeMode POINTWISE_EDGES_PIPELINED

Set job edges with ForwardPartitioner or RescalePartitioner to be ResultPartitionType.PIPELINED_BOUNDED and other edges to be ResultPartitionType.BLOCKING.

ALL_EDGES_PIPELINED

public static final GlobalDataExchangeMode ALL_EDGES_PIPELINED

Set all job edges ResultPartitionType.PIPELINED_BOUNDED.

ALL_EDGES_PIPELINED_APPROXIMATE

public static final GlobalDataExchangeMode ALL_EDGES_PIPELINED_APPROXIMATE

Method Detail

values

public static GlobalDataExchangeMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

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

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static GlobalDataExchangeMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
