Could you build this?
No Implementing a fully compliant, production-grade in-memory database in safe Rust that passes 99% of Valkey/Redis's exhaustive test suite requires deep distributed systems, network protocol, and database internals engineering.
What it would actually take: The project requires implementing the RESP2/RESP3 protocol, complex data structures (skiplists, ziplists, radix trees) within Rust's strict ownership model, event-loop concurrency (e.g., Tokio or custom mio loops), and replication/persistence engines (RDB/AOF). Passing >99% of the official test suite means handling hundreds of subtle edge cases, atomic multi-key commands, and Lua scripting integration. This demands senior systems and database software engineering expertise.
