CloudNativePG is a Kubernetes operator designed for the administration, lifecycle management, and high availability of PostgreSQL database clusters. It functions as a declarative orchestrator that manages database instances through custom resources and manifests. The project distinguishes itself by automating complex operational tasks, including primary election and failover management via streaming physical replication. It provides specialized tools for database version migrations, supporting both offline in-place upgrades and online migrations through logical replication. The operator cove

SQLCipher is an encrypted SQLite database engine and secure relational database that provides transparent AES-256 encryption for database files and stored data. It functions as a cryptographic storage engine that requires a passphrase or binary key to unlock and access content. The engine ensures data confidentiality through page-level encryption and protects data integrity using cryptographic hashes to detect unauthorized modifications. It includes capabilities for encryption key rotation to update passphrases and secure memory locking to prevent sensitive keys from being swapped from RAM to

Pebble is an embedded key-value storage engine written in Go, designed as a library that provides durable, write-optimized data persistence directly within applications. It organizes data using a log-structured merge-tree (LSM-tree) structure, where writes are first buffered in an in-memory skiplist memtable and persisted to a write-ahead log before being flushed to block-based SSTable files on disk. The engine supports atomic batch commits, configurable write synchronization, and automatic background compaction that merges and rewrites sorted runs to reclaim space and maintain read performanc

Pigsty est une plateforme d'orchestration d'infrastructure de base de données complète conçue pour automatiser le cycle de vie complet des clusters PostgreSQL à haute disponibilité. Il fonctionne comme un framework d'infrastructure en tant que code qui gère la coordination des clusters, le provisionnement des nœuds et la découverte de services via des playbooks idempotents. En intégrant des mécanismes de consensus distribués, la plateforme assure un basculement automatisé et une application cohérente de l'état à travers divers environnements, y compris le matériel nu et l'infrastructure virtualisée. La plateforme se distingue par une suite robuste de capacités opérationnelles qui s'étendent au-delà de la gestion de base de données standard. Elle dispose d'un pipeline d'observabilité intégré qui agrège les métriques, les logs et les traces dans des tableaux de bord centralisés pour une surveillance des performances en temps réel et une analyse diagnostique. De plus, elle fournit un framework de migration qui émule les protocoles filaires propriétaires et la syntaxe SQL, permettant l'intégration de charges de travail de base de données d'entreprise héritées dans des environnements relationnels modernes. Le système couvre une large surface fonctionnelle, y compris la gestion avancée du stockage avec clonage par copie sur écriture pour un déploiement rapide, et l'orchestration multi-base de données qui coordonne les moteurs relationnels avec la mise en cache et le stockage d'objets. Il intègre également le renforcement de la sécurité, la sauvegarde et la récupération automatisées, et le routage du trafic via des proxys en couches pour découpler les connexions client de la topologie de cluster sous-jacente. Le projet est distribué sous forme de modèle de miroir de package autonome, permettant un déploiement et une gestion des dépendances cohérents dans des environnements sécurisés ou isolés.

Pigsty is a full-stack orchestration suite for deploying, monitoring, and managing high-availability PostgreSQL clusters and their supporting infrastructure. It functions as a cluster management platform and high-availability suite that automates failover, manages virtual IPs, and ensures data consistency through distributed consensus. The project distinguishes itself by providing a comprehensive database infrastructure-as-code framework and a dedicated observability stack. It incorporates a backup and recovery manager supporting point-in-time recovery via S3-compatible object storage, alongs

RedisShake is a migration and synchronization tool for Redis and Valkey instances. It facilitates the transfer of data between standalone, sentinel, and cluster deployments, acting as a cross-version database migrator and a utility for restoring data from backup files. The project provides a programmable data transformation pipeline that allows for filtering keys, remapping database indices, and executing Lua scripts to modify commands and keys during transit. It supports zero-downtime synchronization by replicating snapshots and streaming incremental changes in real time. The tool covers a

RavenDB is a multi-model NoSQL document database designed for high-performance, ACID-compliant data storage. It persists structured information as schema-flexible JSON documents and utilizes a unit-of-work session pattern to track entity changes and batch modifications into atomic transactions. The platform is built on a distributed architecture that supports horizontal scaling through sharding and ensures high availability via multi-node, master-to-master cluster replication. The database distinguishes itself through a self-optimizing query engine that automatically creates and maintains ind

This project is a proposal for a new immutable date and time API in JavaScript. It serves as a precision time-tracking library and a multi-calendar date engine designed to replace the legacy Date object. The system is distinguished by its support for multiple calendar systems beyond the ISO standard and its use of IANA-based time zone resolution. It provides a framework for managing daylight saving transitions and UTC offsets while maintaining nanosecond precision for global timestamps. The API covers broad functional areas including complex date and time arithmetic, locale-aware formatting,

DDEV is a container-based local development environment and project manager designed to bootstrap consistent web development stacks. It orchestrates Docker containers to provide isolated Linux environments, integrating web servers, databases, and language runtimes. The project distinguishes itself by automating the complexities of local networking and security, featuring a local HTTPS proxy for SSL certificate automation and wildcard DNS for hostname management.
