[Verse 1]
When metadata needs a home to stay
Five-nine-five builds the quorum way
Raft consensus keeps the truth in line
Controllers vote and data's aligned
[Chorus]
KRaft evolution, step by step we grow
Six-three-oh snapshots, seven-six-two knows
Rack awareness guides the leader choice
Eight-three-three production, eight-five-three membership voice
Nine-six-six eligible, replicas in the flow
[Verse 2]
Snapshots capture state when logs get long
Six-three-oh compression keeps performance strong
No more endless replay from the start
Compact images play the smarter part
[Chorus]
KRaft evolution, step by step we grow
Six-three-oh snapshots, seven-six-two knows
Rack awareness guides the leader choice
Eight-three-three production, eight-five-three membership voice
Nine-six-six eligible, replicas in the flow
[Verse 3]
Seven-six-two spreads controllers wide
Rack topology becomes our guide
Network failures won't bring chaos down
Geographic wisdom wears the crown
[Bridge]
Eight-three-three declares we're ready now
Production workloads, take the vow
ZooKeeper's legacy fades away
Modern architecture rules the day
[Verse 4]
Eight-five-three reshapes the member list
Dynamic changes can't be missed
Controllers join and leave with grace
Smooth transitions keep the pace
[Chorus]
KRaft evolution, step by step we grow
Six-three-oh snapshots, seven-six-two knows
Rack awareness guides the leader choice
Eight-three-three production, eight-five-three membership voice
Nine-six-six eligible, replicas in the flow
[Outro]
Nine-six-six selects who leads the dance
Eligible replicas get their chance
From metadata quorum to production might
KRaft's progression burns forever bright
