*Hi all, I open PIP-405 to enhanced dynamic handling of selective consumers in MultiTopicConsumers.*
https://github.com/apache/pulsar/pull/23895/files *In Pulsar, consumers can subscribe to multiple topics by pattern or by passing a list of topics.However, currently, if you need to modify this pattern, it often requires shutting down the existing consumers and creating new consumers with the new pattern.This is because in MultiTopicConsumer, each operation is applied to all consumers.We hope to dynamically add or remove certain topics without affecting other subscribed topics.We want a way to unsubscribe or close from certain consumers and add new ones without restarting the entire consumer.Additionally, these changes should remain optional for users who do not need them.This helps developers experiment with dynamic subscription capabilities without cluttering the core consumer interface.* Thanks, sinan
