[Verse 1]
When clusters grow and tenants multiply
Each needs their slice but can't monopolize
Metadata quotas keep the balance tight
Controllers watching every byte in flight
Rate limits guard the gates from overflow
While partitions dance in separate rows
[Chorus]
Multi-tenant, quota-bent
Keep the boundaries permanent
Isolate, allocate, never saturate
Controller's keeping order straight
MQR - Metadata, Quota, Rate
Three pillars holding cluster fate
[Verse 2]
Topic creation hits the ceiling fast
When quotas strike, the limits hold steadfast
Produce requests get throttled at the door
Consumer groups can't flood the broker core
Each tenant lives within their walled domain
The controller holds the master chain
[Chorus]
Multi-tenant, quota-bent
Keep the boundaries permanent
Isolate, allocate, never saturate
Controller's keeping order straight
MQR - Metadata, Quota, Rate
Three pillars holding cluster fate
[Bridge]
Resource pools divided clean
CPU slices, memory lean
Namespace barriers lock and key
Tenant A can't see Tenant B
Controller's brain distributes load
Down the KRaft consensus road
[Verse 3]
Authentication seals each tenant tight
Authorization checks every right
Network policies route the traffic flow
Resource tags tell the system what to know
Metrics isolated, logs compartmentalized
Shared infrastructure, privatized
[Chorus]
Multi-tenant, quota-bent
Keep the boundaries permanent
Isolate, allocate, never saturate
Controller's keeping order straight
MQR - Metadata, Quota, Rate
Three pillars holding cluster fate
[Outro]
When thousands share one cluster space
KRaft controllers set the pace
Boundaries drawn, resources measured
Multi-tenancy properly treasured
