I am working for data engineering consultancy company and I noticed that we often need large datasets for various reasons, but it's hard to find those. So we started building open source tool which allows us to quickly generate large volumes of data. The idea is to create DSL for describing the data and allowed values and the generator should generate the data set based on that.

Any help and ideas are more than welcome.
