Crate rskv 

rskv: A High-Performance Key-Value Store in Rust

rskv is a high-performance, concurrent, persistent key-value store inspired by Microsoft’s FASTER. It leverages modern Rust features for safety and performance.

Core Features

• Hybrid Storage Engine: Combines in-memory hot data with disk-backed log
• Concurrent Hash Index: Lock-free hash index for fast key lookups
• Non-Blocking Checkpoints: Consistent snapshots without pausing operations
• Epoch-Based Garbage Collection: Safe background space reclamation

Example

use rskv::{RsKv, Config};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = Config::default();
    let kv_store = RsKv::new(config).await?;
     
    let key = b"hello".to_vec();
    let value = b"world".to_vec();
     
    kv_store.upsert(key.clone(), value).await?;
    let result = kv_store.read(&key).await?;
     
    println!("Value: {:?}", result);
    Ok(())
}
