Batching (mengelompokkan pesan) dan compression (mengompresi data) adalah teknik utama untuk throughput Kafka yang tinggi — mengurangi overhead per-pesan dan biaya jaringan/penyimpanan. Memahami keduanya membantu mencapai performa tinggi Kafka.
Batching — kelompokkan pesan
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
