Kafka AlterClientQuotas Response Wire Format v0 — Binary Protocol Layout

What is AlterClientQuotas?

Sets per-user or per-client-id throughput quotas via kafka-configs.sh --alter --entity-type. Quotas are enforced per broker and can be scoped to user level, client-id level, or their intersection. A missing entry means the default quota applies (unlimited if not configured).
