Data warehouse replacement at half the cost

Case Study

Otto GmbH is Germany’s largest e-commerce site for home and living, and one of the first retailers to take its mail-order business online more than 25 years ago. Today, customers of the Hamburg-based company search 3 million products from 6,800 brands, and make 55 percent of purchases on smartphones and tablets. Otto’s data scientists use object-centric processing to analyze customer interactions across channels for a personalized shopping experience. Its team turned to Exasol as they began to process increasing volumes of data.

Überblick

The challenge

Otto planned to use Exasol as an access layer, taking data from a data lake and warehouse to process reports. But the feeder system data structures retained twice as much data, requiring an overly complex loading path. They needed a solution behind the data warehouse to get data to Tableau quickly.


The solution

Midway through the PoC, Otto replaced its data warehouse with Exasol, retaining Hadoop as a raw data store. We quickly learned Otto’s security requirements meant going beyond a new database. Together with their team, we implemented a spark connector as part of a joint hackathon with Otto, Exasol, and partners.


“Exasol’s analytics database proved impressive. Primarily due to an excellent price-performance ratio: low costs coupled with exceptional performance and integration with Hadoop.”

Andreas Bonet, Product Owner at Otto
