README
Generic value log implementation for key-value separated storage, inspired by RocksDB's BlobDB [1] and Titan [2] and implemented in safe, stable Rust.
[!NOTE] This crate is intended as a building block for key-value separated storage. You probably want to use https://github.com/fjall-rs/fjall instead.
Features
- Thread-safe API
- 100% safe & stable Rust
- Supports generic KV-index structures (LSM-tree, ...)
- Generic per-blob compression (optional)
- In-memory blob cache for hot data (can be shared between multiple value logs to cap memory usage)
- On-line garbage collection
Keys are limited to 65536 bytes, values are limited to 2^32 bytes.
Feature flags
serde
Enables serde derives.
Disabled by default.
bytes
Uses bytes as the underlying Slice type.
Disabled by default.
Stable disk format
The disk format is stable as of 1.0.0.
