Leaves: Distributed ID Generation Service

This is a unofficial port of Leaf.

🏠 Homepage

Features

• generate id in segment mode
• generate id in snowflake mode
• mysql
• redis
• postgresql
• sqlite
• mongodb
• runtime-agnostic(tokio or async-std) when using mysql or postgres
• lazy mode: fetch leaf by tag lazily and needs remove it manually
• http server or rpc service(actually just implement it by yourself 😂)

TODO

• performance
• correctness

Example

Enabling the mysql and runtime-tokio feature:

use leaves::dao::MySqlLeafDao;
use leaves::{SegmentIDGen, Config, Result};

#[tokio::main]
async main() -> Result<()> {
    let dao = Arc::new(MySqlLeafDao::new("mysql://...").await?);
    let mut service = SegmentIDGen::new(dao, Config::new());
    service.init().await?;
    let tag = 1;
    for _ in 0..1000 {
        println!("{}", service.get(tag).await?);
    }
}
