Redisson is a feature-rich Java client for Valkey and Redis that extends basic key-value storage with distributed Java collections, objects, and services. It provides synchronous, asynchronous, and reactive APIs for Redis operations, along with integrations for popular frameworks like Spring, Micronaut, Quarkus, and Hibernate. The library implements advanced Redis features including streams, geo-spatial indexing, pub/sub, bloom filters, and distributed computing primitives. Its architecture features a clean separation between core Redis protocol handling, codec-based serialization, and framework-specific adapters, making it a versatile tool for building distributed applications with Redis as a backend.
ShapeShift is a Kotlin/Java library for intelligent object mapping and conversion between objects. It provides multiple ways to define mappings including annotations, a Kotlin DSL, and a Java Builder API. The library features automatic mapping, custom type transformers, conditional mapping, decorators for post-processing, and seamless Spring Framework integration. Its architecture cleanly separates mapping definition resolution from the core mapping engine, making it extensible and flexible.
