[jira] [Created] (KAFKA-20497) ReadOnlyView implementations for wrapping stores

Nicholas Telford created KAFKA-20497:
----------------------------------------

             Summary: ReadOnlyView implementations for wrapping stores
                 Key: KAFKA-20497
                 URL: https://issues.apache.org/jira/browse/KAFKA-20497
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Nicholas Telford
            Assignee: Nicholas Telford


Each of the {{Caching*Store and}} {{Metered*Store}}  implementations need to provide a custom {{ReadOnlyView}} store implementation that implements their domain logic (caching/metering) on a read-only version of their {{wrapped()}} store (via: {{wrapped().readOnly(isolationLevel).}}

{{{}ChangeLogging*Store{}}}s can simply delegate to {{{}wrapped().readOnly(isolationLevel){}}}, because read-only stores do not log any changes.
