Real-Life Use Case
Industry:
Retail and E-Commerce
About:
Groupon is an American e-commerce marketplace, which connects subscribers with local merchants by offering various activities, travel, goods, and services in 15 countries worldwide. By March 2015, it was already serving around 48.1 million active customers and featured in more than 425,000 active deals globally in 48 countries. Groupon’s business model has reformed the companies’ way of reaching out to new customers. Irrespective of the reasons, Groupon reaches out to more people, that too more directly and quickly compared to any other medium.
Challenges:
- The business activities of Groupon majorly rely upon its IT infrastructure. The exceptional growth of the company in a span of just a few years ended up in putting a considerable amount of pressure on its IT infrastructure.
- The enormous amount of data which is said to be the lifeline of Groupon became a huge challenge to deal with. On an average, the company had to process around one Terabyte of raw data every day, that too in real time.
- Moreover, they also had to store this processed information across various databases.
Where Talend Helped:
Groupon uses Talend’s Data Integration products for importing the raw data from different sources to the data warehouse, then transforming it into the desired format and then exporting it to various target systems.
How it actually works?
From over 30 countries, Groupon gathers the customer data, which is loaded into the data warehouse using the Talend integration platform. Groupon handles millions of transactions per day with the help of an OLTP solution which runs on a PostgreSQL database. The Talend platform then replicates data from the OLTP system to the Teradata warehouse after every 5 minutes interval. Along with this, the customer data is also loaded from different data sources to the Salesforce CRM solution. On an hourly basis, this data is further synchronized with the data warehouse in order to ensure that Groupon always has a single source of truth.
So, the ultimate objective of the Talend integration platform is to import data from various sources like CRM, e-mail marketing, and OLTP systems, and move it to the data warehouse as swiftly as possible. This aggregated data is then made available to the sales team to support strategic decisions.
Result:
- 1 TB of raw data is being processed in real time and stored in various target systems every day
- 1,000 data integration jobs are executed on a daily basis using ETL processes
- In every 5 minutes, Talend updates the data warehouse with the OLTP system data
“With Talend, we analyze 1 terabyte of customer data in real time which helps us identify
trends as they emerge.”-Rafael Herrera, Head of BI International, Groupon GmbH
