Could you build this?
No Writing a custom database from scratch in Rust requires deep systems programming skills covering storage engines, B-trees/LSM-trees, ACID transactions, and disk serialization.
What it would actually take: The project requires writing an on-disk storage engine with custom paging (slotted page architecture or LSM tree), a buffer pool manager, write-ahead logging (WAL) for crash recovery, and concurrency control like MVCC or 2PL. The hard parts are preventing data corruption during arbitrary crashes, handling cache eviction under lock contention, and writing an efficient query execution engine. This requires advanced systems programming and database internals engineering expertise.
