What is DBEst‘’s workload like? #2
Description
Hi qingzhi,
The paper mentions that the queries are randomly generated. Could you offer me the TPC-DS workload, CCPP workload and Beijing PM2.5 workload? How do you randomly generate the queries and what are the queries like? I am really grateful if you could tell me the details. My email: liyun@dbis.nankai.edu.cn.
By the way, you use relative error as metric, what is the definition of relative error? How to calculate ?
Thanks.
