apalis
Features
- Simple and predictable job handling model.
- Jobs handlers with a macro free API.
- Take full advantage of the tower ecosystem of middleware, services, and utilities.
- Runtime agnostic - Use tokio, smol etc.
- Optional Web interface to help you manage your jobs.
apalis job processing is powered by tower::Service
which means you have access to the tower middleware.
apalis has support for:

Getting Started
To get started, just add to Cargo.toml
[dependencies]
apalis = { version = "0.6" }
apalis-redis = { version = "0.6" }
# apalis-sql = { version = "0.6", features = ["postgres"] } # or mysql, sqlite
Usage
use apalis::prelude::*;
use apalis_redis::{RedisStorage, Config};
use serde::{Deserialize, Serialize};
#[derive(Debug, Deserialize, Serialize)]
struct Email {
to: String,
}
/// A function that will be converted into a service.
async fn send_email(job: Email, data: Data<usize>) -> Result<(), Error> {
/// execute job
Ok(())
}
#[tokio::main]
async fn main() -> {
std::env::set_var("RUST_LOG", "debug");
env_logger::init();
let redis_url = std::env::var("REDIS_URL").expect("Missing env variable REDIS_URL");
let conn = apalis_redis::connect(redis_url).await.expect("Could not connect");
let storage = RedisStorage::new(conn);
Monitor::new()
.register_with_count(2, {
WorkerBuilder::new(format!("email-worker"))
.data(0usize)
.backend(storage)
.build_fn(send_email)
})
.run()
.await
}
Then
//This can be in another part of the program or another application eg a http server
async fn produce_route_jobs(storage: &RedisStorage<Email>) -> Result<()> {
let mut storage = storage.clone();
storage
.push(Email {
to: "test@example.com".to_string(),
})
.await?;
}

Storage Comparison
Since we provide a few storage solutions, here is a table comparing them:
Feature | Redis | Sqlite | Postgres | Sled | Mysql | Mongo | Cron |
---|---|---|---|---|---|---|---|
Scheduled jobs | ✓ | ✓ | ✓ | x | ✓ | x | ✓ |
Retry jobs | ✓ | ✓ | ✓ | x | ✓ | x | ✓ |
Persistence | ✓ | ✓ | ✓ | x | ✓ | x | BYO |
Rerun Dead jobs | ✓ | ✓ | ✓ | x | ✓ | x | x |
How apalis works
Here is a basic example of how the core parts integrate
sequenceDiagram
participant App
participant Worker
participant Backend
App->>+Backend: Add job to queue
Backend-->>+Worker: Job data
Worker->>+Backend: Update job status to 'Running'
Worker->>+App: Started job
loop job execution
Worker-->>-App: Report job progress
end
Worker->>+Backend: Update job status to 'completed'
