A multi-threaded, Redis-compatible in-memory data store written in C++20. Existing clients connect unchanged. Vector search, a semantic cache for LLM response and agent memory run inside the server. Benchmarks with Redis, Valkey and Dragonfly are public.

Could you build this?
No A multi-threaded, Redis-protocol-compatible in-memory database in C++20 with competitive benchmarks requires deep systems programming, concurrency expertise, and years of performance tuning that vibe coding cannot supply.
What it would actually take: The core is a C++20 server with a lock-free or sharded data structure layer, RESP protocol parsing, and full Redis command coverage for client compatibility. Vector search and semantic caching need ANN indexes (e.g., HNSW) and embedding integration. Building it credibly requires experienced database and systems engineers plus rigorous benchmarking.
