The Mix-and-Match Database (also known as Polyglot Persistence) tutorial illustrates how KurrentDB can project event data into multiple backends, such as PostgreSQL for relational queries and Redis for fast key-value access. This ability to synchronize across systems in real-time enables responsive, scalable, flexible architectures that are optimized for specific use cases. The tutorials provide code samples and hands-on experience with event-driven design.
