Enum Constant Detail

BOUNDED_IN_MEMORY

@EnumFieldDescription(value="Executor which orchestrates concurrent producers and consumers communicating through a bounded in-memory message queue using LinkedBlockingQueue. This queue will use extra lock to balance producers and consumers.")
public static final ExecutorType BOUNDED_IN_MEMORY

DISRUPTOR

@EnumFieldDescription(value="Executor which orchestrates concurrent producers and consumers communicating through disruptor as a lock free message queue to gain better writing performance. Although DisruptorExecutor is still an experimental feature.")
public static final ExecutorType DISRUPTOR

SIMPLE

@EnumFieldDescription(value="Executor with no inner message queue and no inner lock. Consuming and writing records from iterator directly. The advantage is that there is no need for additional memory and cpu resources due to lock or multithreading. The disadvantage is that the executor is a single-write-single-read model, cannot support functions such as speed limit and can not de-couple the network read (shuffle read) and network write (writing objects/files to storage) anymore.")
public static final ExecutorType SIMPLE

Method Detail

values

public static ExecutorType[] 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 (ExecutorType c : ExecutorType.values())
    System.out.println(c);

Returns:

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

valueOf

public static ExecutorType 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
