# R-3PO -- Richard's Parallel Processing Pipeline

## Introduction

A library built on top of [Ray](https://github.com/ray-project/ray)
to make embarassingly parallel problems embarassingly easy.

Suppose you have lots of data files that
need to be processed in the exact same way with the same function.
And suppose you want to save the results of that processing into a CSV file.
This is an _embarassingly parallel_ problem: it should be embarassingly easy.

And that's what R3PO aims to deliver: R3PO lets you do it with a `config.yaml`
file and three lines of code.

`config.yaml`:

```yaml
job_name: count_produce
output_path: /home/lieu/dev/r3po/sample/output_dir
processes: 2
source_file_part: .json
source_path: /home/lieu/dev/r3po/sample/produce_log
working_dir: /home/lieu/dev/r3po/sample/working_dir
```

`main.py`:

```python
from r3po import jobbuilder, jobrunner
# Import the function that will be called by your processes
from count_fruits import count_fruits

CONFIG_YAML_FP = './config.yaml'

# Build jobs
jobbuilder.build_jobs(CONFIG_YAML_FP)

# Run jobs
jobrunner.run_jobs(CONFIG_YAML_FP, count_fruits)

```

This will run the function `count_fruits` on all the `.json` files
in `source_path`, and save the results as CSVs in `output_path`
(one row per JSON file).

That's it! R3PO automatically
handles the distribution of tasks to processes,
saves your progress so you can stop and restart the job anytime,
and logs all errors automatically.

## Quickstart (worked example)

[TODO] -- but check the sample directory

## Installation

```bash
pip3 install r3po
```
