Architecture Decision Record (ADR)

Title: Choosing Kafka as an Event-Driven Streaming Platform

Context:

Our system needs to handle high-throughput and low-latency data streams from multiple sources, and provide real-time processing and analytics capabilities. We need to choose a suitable event-driven streaming platform that can handle this workload and integrate with other systems in our architecture.

Decision:

We will use Apache Kafka as our event-driven streaming platform.
