ArcadeDB is a high-performance, multi-model database management system supporting graph, document, key-value, vector, time-series, and search models with polyglot query languages. It's interesting because it combines extreme performance optimizations ('Low Level Java') with broad protocol compatibility (Postgres, Redis, MongoDB wire protocols) and modern AI/ML integrations like built-in MCP servers and vector embeddings.
