Could you build this?
No Creating a reliable, high-throughput Redis drop-in replacement with distributed caching semantics requires expert-level systems programming, lockless concurrency, memory efficiency, and complex distributed protocol handling.
What it would actually take: The stack would typically be Rust using Tokio or io_uring for zero-copy async networking, parsing the Redis Serialization Protocol (RESP/RESP3), and managing a custom concurrent hash map with custom eviction algorithms (LRU/LFU) and AOF/RDB persistence. For distributed support, it needs cluster gossip protocols, sharding, and consistent hashing. This requires veteran systems software engineers specializing in high-concurrency storage engines.
