FalkorDB is a graph database implemented as a Redis module, written in Rust. It supports the Cypher query language and uses sparse matrices and GraphBLAS/LAGraph for efficient graph operations. The system features MVCC for concurrency control, a batch-oriented query execution engine, and pluggable indexing (including native FalkorDB index for range, full-text, and vector search). Key architectural layers include the Redis module interface, query parser/planner, runtime operators, and storage backend. The codebase demonstrates strong modularity and includes several reusable patterns such as copy-on-write for MVCC, a storage backend seam, thread-local string interning, batched result emission, and a pipeline of query optimization passes.
