Real-time Data Processing with Go, Elastic Beanstalk, and Redshift

Project Overview

This project demonstrates a real-time data processing pipeline using a Go application. The application processes data stored in S3 and stores the results in Redshift. The Go application is deployed using Elastic Beanstalk.

Objective

• Create a real-time data processing pipeline with a Go application.
• Deploy the application using Elastic Beanstalk.
• Store processed data in Amazon Redshift.
• Verify data processing and storage using SQL queries in Redshift.

Prerequisites

Ensure you have the following installed on your local machine:

• Docker
• Docker Compose
• Go

AWS Setup

1. Download Dataset

   • Download the Online Retail dataset from UCI Machine Learning Repository.

2. Create an S3 Bucket

   • Follow the instructions to create an S3 bucket.

3. Upload the Dataset to S3

   • Upload the Online Retail CSV file to the S3 bucket you created. Instructions can be found here.

4. Create a Redshift Cluster

   • Follow the steps to create a Redshift cluster.

5. Create a New Database within the Redshift Cluster

   • Once your Redshift cluster is created, use the AWS Management Console or AWS CLI to create a new database within the cluster.

.env Variables

# To read from S3:
REGION=
BUCKET=
KEY=     #name of the .csv file in S3

# To push data to Redshift:
AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
REDSHIFT_CONN_STRING=

Run with Docker

docker-compose build
docker-compose up

# To print the processed data:
curl "http://localhost:8080?action=print"
(note: the data is printed in the Docker container's console, not where curl is called)

# To insert processed data into Redshift:
curl "http://localhost:8080?action=insert"

Run without Docker

go mod tidy

# To print the processed data:
go run main.go -action=print

# To insert processed data into Redshift:
go run main.go -action=insert
