[Verse 1]
ZooKeeper's reign is fading fast, coordination's changing guard
KRaft mode rises, self-contained, no external keeping hard
Strimzi charts this evolution, roadmap drawn with careful lines
Preview status, not production, but the future it defines
[Chorus]
KRaft removes the keeper's burden
Controller nodes, the cluster's curtain
No more zoo, just Kafka pure
KafkaNodePool makes roles sure
Combined or split, you choose the way
Metadata flows where brokers stay
[Verse 2]
Migration pathways wind through versions, careful steps from old to new
Backup first your precious data, rolling updates see you through
Controller-only nodes stand watching, metadata guardians of state
Combined nodes wear double hats, both controller and data's fate
[Chorus]
KRaft removes the keeper's burden
Controller nodes, the cluster's curtain
No more zoo, just Kafka pure
KafkaNodePool makes roles sure
Combined or split, you choose the way
Metadata flows where brokers stay
[Bridge]
KafkaNodePool CRD arrives
Role-based management comes alive
Controller replicas decide the quorum size
Broker pools scale where your data flies
[Verse 3]
Three controllers minimum needed, quorum math protects your cluster
Odd numbers prevent split-brain, consensus keeps away the bluster
Strimzi wraps complexity, Kubernetes native all the way
Custom resources guide the transition to KRaft's brighter day
[Chorus]
KRaft removes the keeper's burden
Controller nodes, the cluster's curtain
No more zoo, just Kafka pure
KafkaNodePool makes roles sure
Combined or split, you choose the way
Metadata flows where brokers stay
[Outro]
Preview today, production tomorrow
KRaft mode leads where clusters follow
Self-sufficient, streamlined, clean
The future's here, the change is seen
