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 是一个全面的数据库基础设施编排平台，旨在自动化高可用 PostgreSQL 集群的全生命周期。它作为一个基础设施即代码（IaC）框架，通过幂等 Playbook 管理集群协调、节点配置与服务发现。通过集成分布式共识机制，该平台确保了在包括裸机与虚拟化基础设施在内的多样化环境中，自动化故障转移与一致的状态强制执行。 该平台通过一套超越标准数据库管理的强大运营能力脱颖而出。它具备内置的观测流水线，将指标、日志与追踪聚合到集中式仪表盘中，用于实时性能监控与诊断分析。此外，它还提供了一个模拟专有线路协议与 SQL 语法的迁移框架，允许将遗留企业数据库工作负载集成到现代关系型环境中。 该系统涵盖了广泛的功能面，包括带有写时复制（CoW）克隆以实现快速部署的高级存储管理，以及协调关系型引擎与缓存及对象存储服务的多数据库编排。它还整合了安全加固、自动化备份与恢复，以及通过分层代理进行的流量路由，以将客户端连接与底层集群拓扑解耦。 该项目以自包含的包镜像模型分发，能够在安全或离线环境中实现一致的部署与依赖管理。

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 是一个用于 Redis 和 Valkey 实例的迁移与同步工具。它促进了独立部署、哨兵模式和集群部署之间的数据传输，充当跨版本数据库迁移器以及从备份文件恢复数据的实用程序。 该项目提供了一个可编程的数据转换流水线，允许在传输过程中过滤键、重映射数据库索引以及执行 Lua 脚本来修改命令和键。它通过实时复制快照和流式传输增量更改，支持零停机同步。 该工具涵盖了多种提取方法，包括基于复制的迁移、基于扫描的迁移和备份文件恢复。它包括集群节点发现、哨兵主节点解析和版本兼容性验证功能，以确保跨版本传输过程中的稳定性。

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.
