AionDB is a multimodal database engine written in Rust that integrates relational, graph, and vector data models into a single system. It implements the PostgreSQL wire protocol to support standard SQL clients, ORMs, and migration tools. The DBMS stores records on disk using a custom storage layer and provides unified access paths for vector similarity search and graph traversal alongside traditional relational queries.
