In the class Named AclCommand,configure SimpleAclAuthorizer,but no need call loadCache. now we have 20,000 topics in kafka cluster,everytime I run AclCommand,all these topics's Alcs need to be authed, it will be very slow. The purpose of this optimization is:we can choose to not load the acl of all topics into memory, mainly for adding and deleting permissions. PR Available here: [https://github.com/apache/kafka/pull/7706] mainly for adding and deleting permissions,we can choose to not load the acl of all topics into memory,then we can add two args "--load-acl-cache" "false" in AclCommand.main;else you don't add these args, it will load the acl cache defaultly. we can choose improve the running time from minutes to less than one second. -- This message was sent by Atlassian Jira (v8.3.4#803005)
