Hello, I have created a PIP for supporting granting/revoking permissions for multiple topics.
In AuthorizationProvider, the authorization interface `grantPermissionAsync(TopicName topicName, Set<AuthAction> actions, String role, String authDataJson)` currently only supports granting permissions to a single topic. If multiple topics need to be authorized under a namespace, the client needs to call the authorization interface concurrently. Since the permissions information are stored in the namespace-level policies, and multiple topics may be on different brokers, concurrent authorization will cause concurrent modification exceptions. Therefore, supporting granting/revoking permissions for multiple topics is very friendly. PIP-383: https://github.com/apache/pulsar/pull/23355 Regards Jiwei Guo (Tboy)
