Producer compression (Kafka)

Producer compression reduces on-wire and on-disk bytes by compressing batch payloads (for example gzip, lz4, zstd). Compression trades CPU on producers and brokers for lower bandwidth and storage. Effective message size in calculators should reflect compression ratio expectations per workload.

Formula: Effective bytes ≈ raw bytes × compression ratio (empirical per codec).
