# rworker [![Travis-CI Build Status](https://travis-ci.org/lecardozo/rworker.svg?branch=master)](https://travis-ci.org/lecardozo/rworker)

Celery worker for R tasks.

## Motivation

The main motivation for this package was the need for executing long running R functions

triggered by [Celery](https://github.com/celery/celery) (asynchronous task queue package for Python).

![Data flow](https://raw.githubusercontent.com/lecardozo/rworker/master/img/rworker.png)

## Usage

##### Start consuming tasks from R

```R

library(rworker)

library(magrittr)

# Broker url

redis_url <- 'redis://localhost:6379'

# Instantiate Rworker object

consumer <- rworker(name='celery', workers=2, queue=redis_url, backend=redis_url)

# Register tasks

(function(){

    Sys.sleep(5)

}) %>% consumer$task(name='long_running_task')

# Start consuming messages

consumer$consume()

```

The `rworker` function returns a `Rworker` object. This object is responsible for registering tasks, listening for messages coming from the message queue and triggering tasks execution on background processes

##### Send tasks from Python

```python

from celery import Celery

worker = Celery('app', broker="redis://localhost:6379/0", backend="redis://localhost:6379/0")

worker.send_task('long_running_task')

```
