gh-ost is a triggerless online schema migration tool for MySQL. It functions as a replication client and table management utility that synchronizes data from a source table to a shadow table using binary logs, allowing for table structure modifications without locking original tables or causing downtime. The tool distinguishes itself by using binary-log-based replication instead of triggers to stream row-based events to a shadow table. It implements load-aware throttling and dynamic performance tuning to adjust migration speed based on server load and replication lag. Users can monitor and ad

This project is a Node.js client for PostgreSQL databases, providing a protocol parser to translate raw binary streams into JavaScript objects. It serves as a driver for executing queries, managing data, and integrating Node.js applications with PostgreSQL backends. The library includes a connection pool manager to reduce network overhead by caching reusable connections and a result streamer that uses cursors to retrieve large datasets incrementally. It also functions as an event listener for subscribing to asynchronous server-side notifications to trigger real-time application events. Broad

This project is an open-source 3D game engine designed for building high-fidelity games, simulations, and cinematic environments. It functions as a robotics simulation platform with native integration for ROS 2 to model robot controllers and sensors. The engine features a multi-threaded Forward+ physically based renderer that supports hardware-accelerated ray tracing and global illumination. The system is built on a modular extension architecture using Gems to add or replace features without modifying core binaries. It includes a native SDK for AWS cloud integration, enabling IAM authenticati

Patroni is a high availability manager and cluster orchestrator for PostgreSQL. It functions as a failover controller that monitors database health and manages leader transitions to ensure continuous availability and consistency across multiple nodes. The system relies on a distributed configuration store client to synchronize cluster state and perform leader election. It supports integration with external consensus services such as Etcd, Consul, and ZooKeeper, and provides specific orchestration capabilities for deploying clusters within Kubernetes environments. The project covers the manag

This project is a PostgreSQL client library and SQL query builder for JavaScript and TypeScript. It provides a low-level database driver and connection manager to handle database sessions, along with a logical replication client for monitoring real-time changes. The library distinguishes itself with a high-performance bulk data streamer that utilizes the database copy command for importing and exporting large datasets. It also implements a logical replication protocol to facilitate real-time database synchronization through change subscriptions and channel-based notifications. The toolset co

Apache Tomcat is an open-source implementation of the Jakarta Servlet, Pages, Expression Language, and WebSocket specifications, serving as a container for running Java web applications. It provides a modular architecture with a servlet container, connector abstraction for multiple I/O models, and a pipeline-based request processing system that handles cross-cutting concerns through composable components. The server supports container-managed security with configurable realms for authentication against JDBC, LDAP, or memory-based credential stores, and offers TLS encryption with optional Open

Ce projet est une traduction en langue chinoise du document de recherche original détaillant le protocole de consensus Raft. Il sert de traduction de recherche technique et de guide de protocole de consensus, rendant les spécifications de l'algorithme Raft accessibles aux sinophones. La documentation couvre les mécanismes fondamentaux des systèmes distribués, notamment l'élection de leader, la réplication de journal et les protocoles de sécurité. Elle fournit une explication détaillée sur la façon de maintenir une source de vérité unique à travers plusieurs serveurs pour atteindre une gestion de cluster tolérante aux pannes. Le matériel aborde la réplication de machine à état distribuée et la gestion de journal. Il couvre des concepts techniques tels que le suivi de vivacité piloté par heartbeat, les élections à timeout aléatoire, le versionnage de cohérence basé sur les termes et le compactage de journal basé sur des snapshots.

Urho3D is a cross-platform 3D game engine written in C++. It uses a component-based scene graph to compose game objects from nodes and attached components, separating transforms from behaviors for modular design. The engine integrates AngelScript and Lua scripting for game logic, uses the Bullet library for physics simulation, and renders scenes with OpenGL or Direct3D through forward, deferred, or light pre-pass pipelines with customizable render passes and shadow mapping. The engine distinguishes itself with a built-in visual scene and UI editor for composing 3D worlds and interface layouts
