Yes. Topics referenced in ./src/kafka/constants/kafka.topic.constant.ts must exist before running. The default topic configuration is 3 partitions and replication factor 3; for sequential guarantees use 1 partition and replication factor 1.

Yes. The repository includes containerization support and implements a hybrid HTTP server plus Kafka microservice architecture; producer modules are global and consumer behavior can be toggled via environment configuration.
