> However, It takes more time to search for policies from the cache when there
> are millions of policies
> As well as The above REST API sometimes gives stable data due to the deleted
> element is present in the Cache
>
> {code:java}
> In PublicAPIsv2 we add the API's which are available in ServiceREST as an API
> and the getPolicyByName is not available as an API in ServiceREST.
> getPolicyByName ---> (/api/service/{servicename}/policy/{policyname}) in
> PublicAPIsv2
> I guess we should add the below API in ServiceREST also for the same.
> getPolicyByName ---> (/policies/service/{serviceName}/policy/{policyName}) in
> ServiceREST
