TurboKV: A Rust key-value store that hits 2.3M writes per second
TurboKV: Insanely fast Rust key-value store
TurboKV is an async embedded key-value store for Rust, offering atomic batches, ordered range scans, configurable durability, compression, and background compaction. Benchmarks on an Apple M4 show it outperforming fjall by up to 4.4x in durable mode, with sequential batch writes exceeding 2.3 million ops/s. The project emphasizes clean shutdown semantics and provides three durability presets: fast, durable, and paranoid.

So… it’s not durable? Durable doesn’t mean “survives a process restart”, it means “durably saved to persistent storage”. For example, this “durable” mode wouldn’t survive power loss.

Every programmer eventually creates own db: https://github.com/antonmedv/medb

I suppose the insane speed is due to this:
> TurboKV's persisted Bloom-filter format uses hardware AES.
Also, built-in LZ4 compression.
I would expect SIMD to be used for scans.

Is an atomic get+delete operation planned?

Embedded could also mean no_std, which this is absolutely not. Still cool though
