What is Cayley?

Cayley is an open-source database specifically designed for Linked Data, inspired by the graph database that underpins Google's Knowledge Graph, which was formerly known as Freebase. This database prioritizes user-friendly design while effectively managing complex data structures; it includes a built-in query editor, visualizer, and Read-Eval-Print Loop (REPL) functionality. It supports a variety of query languages, such as Gizmo, which is modeled after Gremlin, a query language similar to GraphQL, along with MQL, a simplified version aimed at Freebase users. With its modular architecture, Cayley seamlessly integrates with preferred programming languages and backend storage solutions, making it production-ready and well-tested, with numerous companies relying on it for their operational needs. Furthermore, its optimization for application use showcases remarkable performance; for example, it has been demonstrated to handle 134 million quads in LevelDB on standard 2014 hardware, with multi-hop intersection queries—like identifying films featuring both X and Y—executing in around 150 milliseconds. By default, Cayley operates in-memory, reflecting the capabilities of its backend memstore, which significantly boosts its speed and efficiency during data retrieval and manipulation. Overall, Cayley stands as a robust solution for developers aiming to harness linked data in their applications, while its continuous improvements and community support ensure it keeps pace with evolving technological demands.
