JIRA:  KAFKA-9424 - Getting issue details... STATUS

Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

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

we can choose improve the running time from minutes to less than one second

Public Interfaces

Proposed Changes

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

Compatibility, Deprecation, and Migration Plan

  • No impact or migration plan required as this proposal is only adding new methods and not changing any current behaviour.

Rejected Alternatives

As mentioned in the Proposed changes, this is inefficient.

  • No labels
