in-memory-store

What problem does it solve?

Provides a simple, thread-safe in-memory storage pattern to implement CRUD operations for new resource types in Spring MVC demos and lightweight services, removing the need for a persistence layer during prototyping and tests.

Core Features & Use Cases

• Thread-safe store implemented with ConcurrentHashMap to avoid external locking in concurrent environments.
• Deterministic ID generation using UUID.randomUUID() and idiomatic not-found semantics for get and delete operations.
• Suitable for building demo endpoints, integration tests, or prototypes where a full repository or database is unnecessary; do not expose the map directly and avoid creating repository interfaces.

Quick Start

Add an in-memory service backed by a ConcurrentHashMap that generates UUIDs for new resources and exposes create, getById, list (snapshot), and delete methods.
