Problem

We operate a small business lending platform that processes thousands of loan applications per day, with credit decisions made in real time and repayment events streaming in continuously. Our risk team currently runs models on week-old data because there is no reliable near-real-time pipeline. Design a Kafka-based pipeline that delivers loan application events, credit decisions, and repayment data to the risk analytics layer within minutes of occurrence.

Summary

Loan approved. Loan denied. Every decision is an event.
