wedb_standalone

wedb_standalone provides a lightweight, single-node Redis server implementation that executes Redis commands directly on the embedded LSM-Tree engine (wedb_embed) without the consensus overhead of Raft.

🚀 Features

• Direct Storage Dispatching: Bypasses network RPC and Raft log replication for ultra-low microsecond latency.
• Full RESP2 / RESP3 Support: Compatible with all standard Redis clients.
• Embedded & Daemon Modes: Can be run as a standalone background process or embedded inside another Rust server.
• Rich Data Structures: Full support for Strings, Hashes, Lists, Sets, ZSets, Bitmaps, Bitfields, JSON, Streams, and more.

📦 Installation

Add wedb_standalone to your Cargo.toml:

cargo add wedb_standalone

🛠️ Usage Example

use std::sync::Arc;
use wedb_embed::{WeDb, Conf};
use wedb_standalone::handler::handle_cmd;
use webc_cmd::parse_cmd;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let conf = Conf::new("./data/standalone_demo");
    let db = Arc::new(WeDb::open(conf)?);

    let raw_cmd = vec![b"SET".to_vec(), b"foo".to_vec(), b"bar".to_vec()];
    let cmd = parse_cmd(raw_cmd)?;

    let reply = handle_cmd(&db, cmd)?;
    println!("Response: {reply:?}");

    Ok(())
}
