Could you build this?
No A transactional storage engine with MVCC, WAL, and crash recovery requires deep systems expertise, and subtle concurrency and durability bugs are hard to find without it. Vibe coding can produce a toy engine but not a trustworthy one.
What it would actually take: Building a real version means writing a storage layer in a systems language (C, C++, or Rust) with a page manager, B-tree or LSM indexes, a write-ahead log with fsync discipline, and an MVCC visibility model. Crash recovery and isolation need rigorous testing, such as fault injection and Jepsen-style checks, plus engineers who have built databases before.
