[Verse 1] Storage math unfolds in three dimensions clear Retention times throughput, replication near Seven days of messages at fifty meg per second Times your replica factor, disk space is reckoned Multiply and calculate, the bytes will tell their tale Terabytes accumulate when Kafka ships at scale [Chorus] R-T-R, retention throughput replication Size your cluster right with proper calculation Two gigs RAM per broker, four cores spinning fast Network pipes must carry what replication broadcasts [Verse 2] Memory per broker starts at two gigabytes minimum CPU cores quadruple when your workload's growing premium JVM heap settings take their quarter of the RAM Producer batches, consumer groups all need their diagram Monitor your utilization, watch the metrics climb Scale horizontally before you're fighting against time [Chorus] R-T-R, retention throughput replication Size your cluster right with proper calculation Two gigs RAM per broker, four cores spinning fast Network pipes must carry what replication broadcasts [Bridge] Partitions multiply your throughput potential But keep them reasonable, performance is essential Thousand partitions per broker, that's your ceiling line Network bandwidth doubles when replicas align Leader election storms when partition counts explode Choose your shard strategy, balance the load [Verse 3] Bandwidth calculations factor replication streams Producer traffic doubled in your capacity schemes Cross-rack networking carries follower updates Ten gigabit connections prevent replication waits Disk throughput matters when consumers lag behind Sequential writes and reads keep Kafka aligned [Chorus] R-T-R, retention throughput replication Size your cluster right with proper calculation Two gigs RAM per broker, four cores spinning fast Network pipes must carry what replication broadcasts [Outro] Plan your capacity with mathematics sound Storage, CPU, memory, network all compound Kafka clusters prosper when resources align Measure twice, deploy once, performance will shine
