Could you build this?
No Writing a high-performance persistent key-value storage engine requires low-level systems programming, direct I/O management, cache design, concurrency control, and deep hardware optimization.
What it would actually take: Building TidesDB requires deep knowledge of systems languages like C, C++, or Rust, implementing data structures like LSM-trees or B-trees, custom WAL (write-ahead log), and page caches. It requires handling direct I/O (e.g., io_uring), managing memory barriers, cache coherency, and lock-free concurrency primitives. Robust correctness testing also demands Jepsen testing and crash-recovery fuzzing.
