KIP-1134 — Multi-tenancy in Kafka: Virtual Clusters

Discussion BrokerSecurity

Introduces Virtual Clusters as a multi-tenancy layer on top of a shared Kafka cluster, providing each tenant with isolated topic namespaces, quotas, and ACLs through a proxy or broker-side virtualization layer. Operators running multi-tenant Kafka must today either provision separate physical clusters per tenant (expensive, wasteful) or manually partition namespaces with naming conventions and ACLs (error-prone, no true isolation).
