Enum Constant Details

UNORDERED

public static final ParallelConsumerOptions.ProcessingOrder UNORDERED

No ordering is guaranteed, not even partition order. Fastest. Concurrency is at most the max number of concurrency or max number of uncommitted messages, limited by the max concurrency or uncommitted settings.

PARTITION

public static final ParallelConsumerOptions.ProcessingOrder PARTITION

Process messages within a partition in order, but process multiple partitions in parallel. Similar to running more consumer for a topic. Concurrency is at most the number of partitions.

KEY

public static final ParallelConsumerOptions.ProcessingOrder KEY

Process messages in key order. Concurrency is at most the number of unique keys in a topic, limited by the max concurrency or uncommitted settings.

Method Details

values

public static ParallelConsumerOptions.ProcessingOrder[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static ParallelConsumerOptions.ProcessingOrder valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
