ngjaying commented on issue #3224: Function option --subscription-type does not work URL: https://github.com/apache/pulsar/issues/3224#issuecomment-449936557 @jerrypeng I use pulsar function for a complicated scenario. The function need to consume 2 topics (rule, message). Each instance of the function will hold a different set of rules and apply the rule for each message. So the function needs to Shared subscribe to rule and Exclusive subscribe to message. For exclusive subscription, I think each function instance can have a different subscription name so that all function instances can read from the topic. I understand the usage of exclusive subscription is rare for function, but I think it will be more flexible to still provide that option for the users.
