类 RoundRobinPartitionMessageRouterImpl

java.lang.Object

org.apache.pulsar.client.impl.MessageRouterBase

org.apache.pulsar.client.impl.RoundRobinPartitionMessageRouterImpl

所有已实现的接口:

Serializable, MessageRouter

public class RoundRobinPartitionMessageRouterImpl
extends MessageRouterBase

The routing strategy here:

• If a key is present, choose a partition based on a hash of the key.
• If no key is present, choose a partition in a "round-robin" fashion. Batching-Awareness is built-in to improve batching locality.
