Preguntas de Muestra
Elige una respuesta y consulta la explicación para ver cómo funciona la práctica.
A Streams application shows periodic latency spikes every time cache flushes and commits occur. Which metrics and configuration should be reviewed together?
A Streams application maintains a local RocksDB state store for user-session counts. One instance dies and another instance takes over its partitions. What Kafka-backed mechanism lets the replacement rebuild the state store?
A Kafka Streams service has stable input rate but output stops for one partition after a rebalance. Logs show repeated state restore messages and a large changelog restore backlog. Which operational signal best explains the symptom?
A Java producer sends credit-card authorization events with `enable.idempotence=true`, `acks=all`, and retries enabled. A reviewer suggests setting `max.in.flight.requests.per.connection=1` because otherwise retry order can be corrupted. In current Kafka clients, what is the best response?
A producer uses `delivery.timeout.ms=120000`, `request.timeout.ms=30000`, and retries. During a network issue, callbacks fail before the team expects based on retries alone. What should they understand about `delivery.timeout.ms`?
