Project: Kafka
Issue Type: Improvement
Components: admin, tools
Affects Versions: 2.3.1, 2.4.0, 0.10.2.0
Environment: Linux,JDK7+
Reporter: Steven Lu
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.
