This is a Chef cookbook for installing and managing Redis instances and Sentinel. It provides custom resources for installing Redis from packages or source, configuring Redis server instances with systemd service management, and setting up Redis Sentinel for high availability. The cookbook follows modern Chef practices with unified_mode true resources, comprehensive testing, and cross-platform support for Amazon Linux, Debian, Rocky Linux, and Ubuntu. It includes compatibility wrappers for migrating from older attribute-driven configurations to the new resource-based approach.
FreeRedis is a comprehensive .NET Redis client library that supports a wide range of Redis deployment modes including standalone, cluster, sentinel, and pooling. It provides both synchronous and asynchronous APIs for virtually all standard Redis commands (strings, hashes, lists, sets, sorted sets, streams, keys, etc.) and extends into advanced features such as distributed locks with automatic extension (watchdog), delayed queues, client-side caching, and Redis Stack modules like RediSearch, RedisJSON, and Bloom filters. The library also includes an OpenTelemetry integration for distributed tracing and a distributed cache adapter for ASP.NET Core's IDistributedCache interface. The architecture is centered around the `RedisClient` class, which uses a pluggable adapter pattern to handle different connection strategies (e.g., `PoolingAdapter`, `ClusterAdapter`, `SentinelAdapter`). Low-level socket communication is abstracted via `IRedisSocket`, and connection pooling is managed by a generic `ObjectPool<T>` with circuit breaker and health checks. The library also includes an `IdleBus` container for managing multiple connections per endpoint. Command building is handled by `CommandPacket`, which supports key prefixing and AOP interception. The RediSearch module provides a fluent builder pattern and an ORM-like `FtDocumentRepository` that translates C# expressions into RediSearch queries. Key entry points include the `RedisClient` constructors (for pooling, cluster, sentinel, and standalone), the `IRedisClient` interface, and the `FreeRedis.OpenTelemetry` extension for tracing. External dependencies are minimal: the core library targets .NET Standard 2.0, .NET Framework 4.0+, and .NET 8, with optional dependencies on `Microsoft.Extensions.Caching.Abstractions` and `OpenTelemetry`. The library is designed for high performance and low latency, with benchmarks showing competitive throughput against StackExchange.Redis and CSRedisCore.
This repository is a comprehensive multi-module Maven project that serves as a learning and demonstration resource for the Java ecosystem, specifically focusing on Spring Boot, microservices, middleware, and AI integration. It contains over 20 independent modules, each showcasing a specific technology or pattern: from core Spring features (AOP, events, lifecycle) to advanced distributed systems (Dubbo, gRPC, Netty, RocketMQ, Kafka, Redis, Elasticsearch, ShardingSphere, Sentinel, Nacos, Curator) and modern AI capabilities (LangChain4j-based RAG, agentic workflows, guardrails, MCP client, image generation, TTS). The architecture is a modular monolith where each module is independently runnable via its own Spring Boot application class, sharing a common utility library (whatsmars-common) for serialization, caching, consistent hashing, encryption, and logging. The AI module is particularly notable for implementing advanced patterns such as query compression, smart routing, re-ranking, structured output, and configurable agentic workflows (sequential, parallel, conditional, loop, supervisor). While the repository is not a single deployable product, it provides high-quality, well-documented examples that demonstrate non-obvious craftsmanship in areas like custom gRPC load balancing, consistent hashing with virtual nodes, and programmatic logger creation. The codebase is professionally written with good separation of concerns, though testing coverage is limited to utility classes. Overall, it is a valuable reference for Java developers exploring modern frameworks and AI integration patterns.
This repository is a meta-project for a Spring Cloud microservices demo, now superseded by the Opensabre framework. It contains no actual source code; instead, it aggregates several external submodules (opensabre-framework, base-authorization, base-organization, base-gateway, etc.) via Git submodules. The root pom.xml defines dependencies for Spring Boot 2.1.10, Spring Cloud Greenwich, and Alibaba Cloud 2.1.0, all of which are outdated. The README explicitly states that the project has been replaced by a newer version. As a standalone repository, it provides no reusable code or components; it serves only as a historical reference or a pointer to the submodules. The repository is effectively deprecated and should not be used for new projects.
