Simple Job Queue
WIP
A simple (and probably very ineffecient) async distributed job queue with configurable backends. Built for my own use-case, use at your own peril. Currently only supports Tokio.
Feature | Redis |
---|---|
Job submission | ✅ |
Job processing | ✅ |
Distributed workers | ✅ |
Reseliency | ✅ |
Delayed execution | ✅ |
Retries | 🟡 |
Installation
cargo add simple-job-queue
Usage
use std::time::{Duration, SystemTime, UNIX_EPOCH};
use async_trait::async_trait;
use serde::{Deserialize, Serialize};
use simple_job_queue::{
redis::{RedisJobQueueBackend, RedisJobQueueBackendOptions},
Job, JobError, JobQueue, JobQueueOptions, Processor,
};
#[derive(Serialize, Deserialize)]
pub struct Data {
field: i32,
}
pub struct DataProcessor;
#[async_trait]
impl Processor<Data> for DataProcessor {
async fn process(&mut self, job: &Job<Data>) -> Result<(), JobError> {
println!("{}", job.data.field);
Ok(())
}
}
#[tokio::main]
async fn main() {
let backend = RedisJobQueueBackend::new(
"redis://:speakfriendandenter@droplet01.affanshahid.dev",
"queue_name".to_string(),
RedisJobQueueBackendOptions::default(),
)
.unwrap();
let mut queue: JobQueue<Data, RedisJobQueueBackend> =
JobQueue::new(backend, JobQueueOptions::default());
queue.start(DataProcessor).await.unwrap();
queue.submit(Job::new(Data { field: 1 })).await.unwrap();
let now = SystemTime::now()
.duration_since(UNIX_EPOCH)
.expect("Time went backwards")
.as_millis();
queue
.submit(Job::new_delayed(Data { field: 100 }, now + 10_000))
.await
.unwrap();
tokio::time::sleep(Duration::from_secs(15)).await;
}
