Batching (agrupar mensajes) y compresión (comprimir datos) son técnicas clave para lograr alto throughput en Kafka — reduciendo la sobrecarga por mensaje y los costos de red/almacenamiento. Entenderlas ayuda a lograr el alto rendimiento de Kafka.
Batching — agrupar mensajes
BATCHING → the producer groups multiple messages into a single BATCH before sending:
→ fewer, larger requests instead of many tiny ones → much higher THROUGHPUT (less
per-request overhead, fewer network round-trips)
→ controlled by: batch.size (batch size limit) + linger.ms (wait time to accumulate a batch)
→ trade-off: slightly higher LATENCY (waiting to batch) for much higher throughput
→ batching is essential for high-throughput producing
