Motivation
Repeat the
handleMetadataChangescallback whenconfigurationMetadataStoreequalslocalMetadataStore.This is caused by repeatedly registering the same callback
handleMetadataChangesfor the same object in classBrokerService.pulsar.getLocalMetadataStore().registerListener(this::handleMetadataChanges); pulsar.getConfigurationMetadataStore().registerListener(this::handleMetadataChanges);For example, when we perform the update namespaces policies, here we call set-message-ttl:
sh bin/pulsar-admin namespaces set-message-ttl --messageTTL 60 test-tenant/test-nsWe will see the server output two lines of the same log:
