Best Graph Databases for Kubernetes

ArcadeDB is a high-performance, open-source multi-model database that unifies graphs, documents, key-value, search engine, vectors, and time-series data in a single engine. Each model is native — no translation overhead, no external adapters. Built for developers who refuse to compromise: 10M+ records/second, constant graph traversal speed regardless of size, and 6 query languages out of the box — SQL, Cypher (native OpenCypher engine,TCK-compliant), Gremlin, GraphQL, MongoDB API, and Java. Runs embedded in your JVM, standalone, or distributed across an HA cluster using Raft Consensus. ACID-compliant, fully transactional, and extremely lightweight. Stop running five separate databases for five data models. One database. Every model. Apache 2.0 — open source forever.

Cayley is an open-source database tailored for Linked Data, drawing inspiration from the graph database that supports Google's Knowledge Graph, previously known as Freebase. This graph database is crafted for user-friendliness and adept at handling intricate data structures, featuring an integrated query editor, a visualizer, and a Read-Eval-Print Loop (REPL). It supports various query languages, including Gizmo, which is influenced by Gremlin, a GraphQL-like query language, and MQL, a streamlined version catering to Freebase enthusiasts. Cayley's modular architecture allows seamless integration with preferred programming languages and backend storage solutions, making it production-ready, thoroughly tested, and utilized by numerous companies for their operational tasks. Additionally, it is optimized for application use, demonstrating impressive performance metrics; for instance, testing has shown that it can effortlessly manage 134 million quads in LevelDB on consumer-grade hardware from 2014, with multi-hop intersection queries—such as finding films featuring both X and Y—executing in about 150 milliseconds. By default, Cayley is set up to operate in-memory, which is what the backend memstore refers to, thereby enhancing its speed and efficiency for data retrieval and manipulation. Overall, Cayley offers a powerful solution for those looking to leverage linked data in their applications.
