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 este o platformă cuprinzătoare de orchestrare a infrastructurii de baze de date concepută pentru a automatiza întregul ciclu de viață al clusterelor PostgreSQL de înaltă disponibilitate. Acesta funcționează ca un framework de tip infrastructure-as-code care gestionează coordonarea clusterului, provizionarea nodurilor și descoperirea serviciilor prin playbook-uri idempotente. Prin integrarea mecanismelor de consens distribuit, platforma asigură failover-ul automat și impunerea stării consistente în medii diverse, inclusiv bare metal și infrastructură virtualizată. Platforma se distinge printr-o suită robustă de capabilități operaționale care se extind dincolo de gestionarea standard a bazelor de date. Dispune de un pipeline de observabilitate încorporat care agregă metrici, log-uri și urme în dashboard-uri centralizate pentru monitorizarea performanței în timp real și analiză diagnostică. În plus, oferă un framework de migrare care emulează protocoalele wire proprietare și sintaxa SQL, permițând integrarea sarcinilor de lucru ale bazelor de date enterprise legacy în medii relaționale moderne. Sistemul acoperă o suprafață funcțională largă, inclusiv gestionarea avansată a stocării cu clonare copy-on-write pentru implementare rapidă și orchestrarea multi-bază de date care coordonează motoarele relaționale cu caching-ul și serviciile de stocare a obiectelor. De asemenea, încorporează securizarea, backup-ul și recuperarea automată și rutarea traficului prin proxy-uri stratificate pentru a decupla conexiunile clienților de topologia clusterului subiacent. Proiectul este distribuit ca un model de oglindire a pachetelor auto-conținut, permițând implementarea consistentă și gestionarea dependențelor în medii securizate sau izolate (air-gapped).

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 este un instrument de migrare și sincronizare pentru instanțele Redis și Valkey. Acesta facilitează transferul de date între deployment-uri de tip standalone, sentinel și cluster, acționând ca un migrator de baze de date cross-version și ca utilitar pentru restaurarea datelor din fișiere de backup. Proiectul oferă un pipeline programabil de transformare a datelor care permite filtrarea cheilor, remaparea indicilor bazelor de date și executarea de scripturi Lua pentru a modifica comenzi și chei în timpul tranzitului. Suportă sincronizarea fără downtime prin replicarea snapshot-urilor și streaming-ul modificărilor incrementale în timp real. Instrumentul acoperă o gamă largă de metode de extracție, inclusiv migrarea bazată pe replicare, migrarea bazată pe scanare și restaurarea din fișiere de backup. Include capabilități pentru descoperirea nodurilor de cluster, rezoluția master-ului sentinel și verificarea compatibilității versiunilor pentru a asigura stabilitatea în timpul transferurilor între versiuni diferite.

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.
