Roman Numerals Kafka + RDS Postgres App

This project demonstrates a simple producer-consumer pipeline using Apache Kafka with a Postgres RDS backend.
It converts numbers into Roman numerals, publishes them to a Kafka topic, and persists the results in Postgres.

🚀 Architecture

1. Producer

   • Takes an integer as input.
   • Converts it into Roman numerals.
   • Publishes the result to a Kafka topic (roman-topic).

2. Kafka

   • Acts as the message broker.
   • Decouples producer and consumer.

3. Consumer

   • Subscribes to the Kafka topic.
   • Reads incoming messages (number → roman numeral).
   • Inserts results into Postgres RDS.

4. Postgres (AWS RDS)

   • Stores messages in a roman_numerals table.
   • Schema:

     CREATE TABLE roman_numerals (
         id SERIAL PRIMARY KEY,
         number INT NOT NULL,
         roman TEXT NOT NULL,
         created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
     );
