It is highly demanded in most businesses to have the ability of obtaining audit information in case someone changes cluster configuration (like creation/deletion/modify/description of any topic or ACLs).
We may add this ability. Since audit requirements are so broad, it's impractical to support all of them.
Hence we have to provide ability for users to plug resources helping to achieve required capabilities.

Public Interfaces

AuditExtension

Developers will be required to implement only the AuditExtension interface to provide an extension. We provide default implementation of AuditExtension that will send audit events to log file specified in logging properties.
We will provide several implementations of AuditEvent interface likewise there are a lot of audit events like create ACL, delete ACL, create topic, etc.
Moreover, it might be necessary to know which result the operation finishes with. Therefore, it is convenient to have separate event implementation for every audit event.
Every kind of audit event will be implemented by default.
