Batching (raggruppamento di messaggi) e compression (compressione dei dati) sono tecniche chiave per un alto throughput Kafka — riducono l'overhead per messaggio e i costi di rete/storage. Comprenderle aiuta a raggiungere le alte prestazioni di Kafka.
Batching — raggruppare i messaggi
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
