What's next: From Python to production

Path 1: Port the event-loop step (step 9) to Go or Rust. Same architecture. The diff is the implementation language. You will close most of the gap to real Redis. The Go port is the most ergonomic. Rust gives you the closest match. We have a parallel Go workshop coming.

Path 2: Add a missing piece. Pattern subscribe (PSUBSCRIBE), client output buffer limits, AOF rewrite, real binary RDB with checksums, active expiry on a timer. Each is a one-evening project that exercises one part of the design.

Path 3: Read real Redis. Start at redis/src/server.c. You can now navigate it. Look for the dispatch table (commandTable), the event loop (aeMain), the protocol parser (processInputBuffer). The names are different. The shapes are the ones you wrote.
