Get the stats for the Netty allocator. The broker will dispatch the batch to the consumer, so the default batch mechanism may break the Key_Shared subscription guaranteed message distribution semantics. This document is designed to be viewed using the frames feature. Learn more about Pulsar at https://pulsar.apache.org.

Once you've instantiated a By default, producers produce messages that consist of byte arrays. Set maxConsumersPerTopic configuration on a namespace. Set maxProducersPerTopic configuration on a namespace.Set the persistence configuration for all the topics on a namespace. Set maxConsumersPerSubscription configuration on a namespace. Consumer1 will receive:If a topic is a partitioned topic, each partition has only one active consumer, messages of one partition are distributed to only one consumer, and messages of multiple partitions are distributed to multiple consumers.In shared subscription mode, multiple consumers can attach to the same subscription and messages are delivered in a round robin distribution across consumers.If a broker dispatches only one message at a time, consumer1 receives the following information.This is a new subscription mode since 2.4.0 release, create new consumers and subscribe with If batching is enabled at the producer side, messages with different keys are added to a batch by default. Apache Pulsar is a distributed open source Publication/Subscription based messaging system developed at Yahoo.It was created to power Yahoo's critical applications like Yahoo Mail, Yahoo Finance, Yahoo Sports etc. You can specify a timeout to wait for enough messages.The batch receive is completed if any of the following condition is met: enough number of messages, bytes of messages, wait timeout.In addition to subscribing a consumer to a single Pulsar topic, you can also subscribe to multiple topics simultaneously using In the above example, the consumer subscribes to the You can also subscribe to an explicit list of topics (across namespaces if you wish):You can also subscribe to multiple topics asynchronously using the A subscription is identical with the subscription name which can specify only one subscription mode at a time.
Javadoc for the Pulsar client is divided into two domains by package as follows.This document focuses only on the client API for producing and consuming messages on Pulsar topics. Set maxConsumersPerTopic configuration on a namespace. For a full list, see the Javadoc for the Batch receive policy limits the number and bytes of messages in a single batch. You cannot change the subscription mode unless all existing consumers of this subscription are offline.Different subscription modes have different message distribution modes. The following is an example.
