Mickael Maison commented on KAFKA-14357:
----------------------------------------
Looking further into describeClientQuotas() it doesn't quite work like I
thought. Some ClientQuotaFilterComponent can be additive, for example it's
possible to describe quotas for a USER and CLIENT_ID combination. On the other
hand it's not possible to combine them with an IP entity. For this reason it's
probably best to keep the current restrictions, only a single entry per entity
type, on ClientQuotaFilterComponent to preserve the current semantics.
So if we want to describe multiple entities, we should have a collection of
ClientQuotaFilter objects, so we basically end up with an API like the proposed
describeAcls().
{code:java}
Collection<ClientQuotaFilter> filters = Arrays.asList(
ClientQuotaFilter.contains(Collections.singletonList(ClientQuotaFilterComponent.ofEntity(USER,
"user1"))),
ClientQuotaFilter.contains(Collections.singletonList(ClientQuotaFilterComponent.ofEntity(USER,
"user2")))
);
DescribeClientQuotasResult quotas = admin.describeClientQuotas(filters);
{code}

> The Admin API has several methods to describe different objects such as ACLs,
> Quotas or SCRAM-SHA users. But these API seem to be usable only in one for
> the two modes:
> * Query or one users ACLs / Quotas / SCRAM-SHA credentials
> * Query all existing ACLs / Quotas / SCRAM-SHA credentials
> But there seems to be no way how to batch the describe requests for multiple
> users. E.g. {_}describe ACLs of users Joe, John and Mike{_}. It would be nice
> to have such option as it might make it easier for applications using the
> Admin API to make less different API calls.
