Could you build this?
No Writing an embedded storage engine that outperforms RocksDB demands world-class systems engineering, low-level concurrency, LSM-tree architecture, and kernel I/O optimization.
What it would actually take: Building this requires expert knowledge of LSM-trees, write-ahead logs (WAL), cache-oblivious data structures, custom memory allocators, and asynchronous I/O (e.g., io_uring) in C, C++, or Rust. Performance tuning requires deep kernel profiling, lock-free concurrency primitives, and extensive crash-recovery testing (Jepsen/fuzzing).
