What is Memgraph?

Memgraph is a high performance, in memory graph database for real time AI context and graph analytics at scale. Vector search identifies what is similar. Graph reasoning reveals what is connected by traversing relationships, dependencies, and hierarchies that similarity alone cannot capture. Modern AI systems need both. Memgraph provides the graph layer that delivers precise structural context, full auditability, and sub millisecond performance. It powers GraphRAG pipelines, AI memory systems, and agentic workflows through a single high performance layer built for connected, structured context. The same architecture also supports real time graph analytics for fraud detection, network analysis, infrastructure monitoring, and other operational workloads where milliseconds directly affect outcomes. NASA uses Memgraph to connect people, skills, and projects across the agency in a queryable knowledge graph for real time expert discovery and workforce planning. Cedars Sinai uses it to connect genes, drugs, and clinical pathways in an Alzheimer’s knowledge graph spanning more than 230,000 entities, supporting drug repurposing research and multi hop biomedical reasoning. Across cybersecurity, finance, retail, and other knowledge intensive industries, organizations use Memgraph to turn connected data into real time insight.

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.
