[Verse 1]
ZooKeeper's reign is fading fast, legacy chains we're breaking
KRaft consensus takes the helm, new metadata awakening
No more ensemble coordination, quorum controllers rise
Raft protocol elections start when leadership dies
[Chorus]
Leader, log, commit the flow
KRaft makes the cluster grow
Meta topics store the state
Controller failover won't make you wait
Raft consensus, three-step dance
Election, replication, advance
[Verse 2]
Metadata log replaces trees, topics hold the cluster brain
Committed entries cascade down, consistency we maintain
Migration paths from old to new, dual-mode lets you slide
Legacy systems bridge the gap while architectures collide
[Chorus]
Leader, log, commit the flow
KRaft makes the cluster grow
Meta topics store the state
Controller failover won't make you wait
Raft consensus, three-step dance
Election, replication, advance
[Bridge]
Kafka four-point-oh arrives, ZooKeeper dependencies severed
Partition limits scale beyond what previous versions weathered
Millisecond failover times, performance bottlenecks dissolved
Controller quorum streamlines what coordination once involved
[Verse 3]
Three-node minimum for safety, five for production load
Metadata replication keeps the cluster episode
No split-brain scenarios, majority rules the vote
Leader election algorithms keep the system afloat
[Chorus]
Leader, log, commit the flow
KRaft makes the cluster grow
Meta topics store the state
Controller failover won't make you wait
Raft consensus, three-step dance
Election, replication, advance
[Outro]
ZooKeeper's chapter closes now, KRaft writes tomorrow's page
Consensus protocols evolve, welcome to the KRaft age
