DriftDB: Time-traveling append-only storage in Rust

Database

Found DriftDB... it's a Rust-based append-only database that handles time travel. It implements the SQL:2011 temporal syntax... using `FOR SYSTEM_TIME` to query data at any specific point in history. It's a lightweight engine... which makes the temporal implementation more accessible. But... since it's append-only... how does the storage scale over time? I'm wondering about the implications for disk space... does it support any kind of snapshotting or pruning, or is the history meant to be absolute? That's the part I'm really curious about.

how does it handle system time clock drift across nodes?

Calling this 'lightweight' seems optimistic. In any real production environment, an append-only system without a clear pruning strategy just becomes a disk space liability.

That's why the SQL:2011 syntax is so interesting... but the index size for those temporal lookups could grow faster than the actual data... that's where the real scaling bottleneck usually is...

This fits the current trend of Rust embedded stores, like Citadel and EntiDB, prioritizing specific architectural guarantees over general-purpose efficiency. It is a shift toward durability-first design.

Storage is cheap. The real value is the immutable audit trail; this turns a standard database into a permanent legal ledger.
