# Notification Engine

Distributed & scalable generic notification(cum cronjob) engine implementation in Golang. Architecture and implementation is inspired from [BigBen](https://github.com/walmartlabs/bigben) by Walmart labs.

## Pre-requisites

- Docker

## Setup

Start a sample 3-node manager and single-node worker system using following command - 

```

make start

```

## Basic Architecture

### Major Components

- PostgresDB as data store

- Etcd v3 for cluster synchronization

- Rabbitmq for job queues

### Services

- Manager Service(s) : Master-slave cluster of a manager to pick up scheduled job from data store and push to worker queue.   

- Worker Service(s) : Idempotent worker for picking jobs from worker queue and executing them.
