// TODO: [Exercise - Kafka Partitioner Configuration]
// When starting the API Gateway, KafkaJS prints a startup warning:
// "KafkaJS v2.0.0 switched default partitioner. To retain the same partitioning behavior..."
// Task: Pass the configuration object inside `kafka.producer(...)` to specify the partitioner:
// 1. Resolve the warning by explicitly selecting the partitioner (e.g. Partitioners.LegacyPartitioner or a custom partitioner).
// 2. Test and verify that events for the same `deviceId` consistently route to the exact same partition topic.
// Tip: import { Partitioners } from 'kafkajs'; and configure it in the producer options:
// export const producer: Producer = kafka.producer({ createPartitioner: Partitioners.LegacyPartitioner });
export const producer: Producer = kafka.producer();
