Kafka with Spring Boot: Production-Ready Configuration

1. Producer Configuration

Properly configuring Kafka Producer is critical for production. This is an important part of microservice system optimization.

spring:
  kafka:
    producer:
      bootstrap-servers: localhost:9092
      key-serializer: org.apache.kafka.common.serialization.StringSerializer
      value-serializer: org.springframework.kafka.support.serializer.JsonSerializer
      acks: all
      retries: 3
      batch-size: 16384
      linger-ms: 10
      compression-type: gzip

2. Consumer Configuration

spring:
  kafka:
    consumer:
      bootstrap-servers: localhost:9092
      group-id: my-group
      auto-offset-reset: earliest
      enable-auto-commit: false
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.springframework.kafka.support.serializer.JsonDeserializer

3. Error Handling

Retry Strategy

Exponential backoff
Dead letter topic
Error handlers

4. Monitoring

Consumer lag monitoring
Throughput metrics
Error rate tracking

5. Best Practices

Idempotent consumers
Transactional producers
Schema registry with Avro/Protobuf

Conclusion

Appropriate Kafka configuration is critical for production systems. If you need support with message queue system optimization or system architecture consulting, please contact for consultation.
