   @StephanEwen 
   Thanks for your push, I’d add README.md file in the rest folder.  
   About data generator and license: 
   (1) I had a survey and tried the alternative Java implementations you 
posted, they are older version and have  no answer set and query template. If 
we use them, we can not validate the accuracy of result although many open 
source SQL system like hive/presto use them. Both hive 、presto、spark didn‘t 
validate the result.
   (2) about the license, the queries generated from templates is constant. 
Could we keep these queries and remove all templates files just like databricks:
   
[spark-sql-perf](https://github.com/databricks/spark-sql-perf/tree/master/src/main/resources/tpcds_2_4)
 ?
