JustAQuote is a high-performance REST API built with Spring Boot, designed for the scalable delivery of daily motivational quotes.
The project showcases backend performance optimization using a Redis, dramatically improving response times under high-read workloads.
The primary technical achievement of this project is a drastic reduction in API response latency by introducing Redis as a distributed caching layer in front of PostgreSQL (The first value is from the database).
Total Improvement: ~98.6% latency reduction 🚀
- Backend: Java 21, Spring Boot (Web, Data JPA, Redis)
- Database: PostgreSQL (Persistent storage)
- Caching: Redis (In-memory data store)
- Containerization: Docker & Docker Compose
- Build Tool: Gradle
-
⚡ Optimized Data Retrieval Implements a cache-aside pattern, querying Redis before PostgreSQL to drastically reduce database load and response latency.
-
📈 Scalable Architecture Designed for high-read, high-concurrency environments by offloading frequent queries to an in-memory cache.
-
🐳 Containerized Environment Fully orchestrated using Docker Compose, enabling one-command startup of the database, and cache.
-
🧱 Clean Architecture Follows a Controller–Service–Repository layering approach to ensure maintainability, testability, and clear separation of concerns.
