The Art of Problem-Solving in Software Engineering: How to Make MySQL Better

Fastfull embedded transactional key-value storage engine ★ Surpasses the legendary LMDB in reliability, capabilities and performance ★ Used in hundreds of open source projects, including Ethereum.

A Modern Embedded SQL Database written in Rust

Nornicdb is a distributed low-latency, Graph+Vector, Temporal MVCC with all sub-ms HNSW search, graph traversal, and writes. Using Neo4j Bolt/Cypher and qdrant's gRPC means you can switch with no changes while adding intelligent features like schemas, managed embeddings, reranking+llm, GPU accel, Auto-TLP, Policy-based Memory Decay, and MCP server.
