About

Exax, previously the Expertmaker Accelerator, is a well-proven data processing framework providing fast data access, parallel execution, reproducibility, and transparency.

Exax can be used for anything from small daily data analysis tasks to running as multi-CPU backend in live production recommender systems based on multi-billion row datasets. It is an excellent tool for data engineering.

The Accelerator is released as open source by eBay under the Apache V2.0 license, and is under constant development.

The Accelerator was developed by the Swedish AI company Expertmaker. The first project using the Accelerator was run in 2012, and since then it has been the core tool in a number of studies and live production recommender systems. In 2016, Expertmaker was acquired by eBay.
