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
• postgres
• runtime-agnostic(tokio or async-std) when using mysql or postgres
• http server or rpc service(actually just implement it by yourself 😂)

TODO

• more configurable
• performance
• MongoDB

Example

Enabling the mysql and runtime-tokio feature:

use leaves::dao::mysql::MySqlLeafDao;
use leaves::LeafSegment;
use leaves::Result;

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

Benchmark

Not yet.But in my PC and local database,I used 10 tasks and each one loop 1000 times. It costs 400ms.
