For years, software developers faced an exhausting architectural dilemma: choose the bulletproof safety, ACID compliance, and relational maturity of traditional databases like PostgreSQL, or embrace the flexible, schema-free, developer-friendly document model of NoSQL options like MongoDB.
Founded in Madrid, Spain, by a team of veteran database engineers and open-source advocates—including prominent technologist Álvaro Hernández Tortosa—8kdata was established to eliminate this false dichotomy. Rather than building a fresh database management system from the ground up (a risky undertaking fraught with journaling, concurrency, and durability hurdles), 8kdata looked upward. They realized that PostgreSQL was already powerful and extensible enough to serve as the bedrock for next-generation data solutions.
Bridging Worlds with ToroDB
8kdata’s crowning technical achievement was ToroDB, an open-source, document-oriented database engine designed to be fully compatible with the MongoDB protocol while running entirely on top of PostgreSQL.
While developers loved MongoDB for its JSON-based document flexibility, scaling it for complex transactional integrity or heavy analytical reporting could introduce friction. ToroDB solved this by allowing applications to natively speak the MongoDB query language, yet decomposing and storing that JSON data cleanly within a relational framework. This approach granted developers the best of both worlds: the expressive, schema-less agility of NoSQL on the front end, paired with the ironclad reliability, high concurrency, and native SQL capabilities of PostgreSQL on the backend.
Open-Source Contribution and Engineering Philosophy
Beyond ToroDB, 8kdata contributed actively to the broader database ecosystem through open-source tooling. Projects like phoebe (an asynchronous PostgreSQL driver toolkit for Java/JVM ecosystems) and performance measurement utilities exemplified their engineering rigor. Their core philosophy centered on the idea that extensibility always beats reinvention.
The Legacy of 8kdata
The data landscape continues to evolve rapidly toward cloud-native abstractions, serverless infrastructures, and specialized vector stores. Yet, the architectural ethos pioneered by 8kdata remains deeply relevant. They demonstrated that legacy and emerging paradigms do not need to exist in silos. By building intelligent bridges between document-based flexibility and relational strength, 8kdata left an enduring mark on how modern engineering teams approach data architecture.
