The DSB benchmark is designed for evaluating both workloaddriven and traditional database systems on modern decision support workloads. DSB is adapted from the widely-used industrialstandard TPC-DS benchmark. It enhances the TPC-DS benchmark with complex data distribution and challenging yet semantically meaningful query templates. DSB also introduces configurable and dynamic workloads to assess the adaptability of database systems. Since workload-driven and traditional database systems have different performance dimensions, including the additional resources required for tuning and maintaining the systems, we provide guidelines on evaluation methodology and metrics to report.

The choice -param_dist doesn't work in Ubuntu22.04

Hi Bailu~
when I run
./dsqgen -input /my_path/dsb/query_templates_pg/agg_queries/templates.lst -OUTPUT_DIR /my_path/dsb_workload/tmp -directory /my_path/dsb/query_templates_pg/agg_queries -dialect postgres -param_dist normal -rngseed 997 in my Ubuntu22.04
I got
ERROR: File 'my_path/dsb/querynormal/query013.tpl' not found
After I remove the "param_dist", it works ok for me. But I am not sure whether the parameter is necessary for me cause I don't exactly understand what role "param_dist" plays(which is not mentioned both in README or the DSB paper, can you explain for me? Thanks so much)

Hi @EvagelineFEI, Thanks for the feedback. The param_dist is used for specifying the distribution of the parameters. By default, the parameters will follow uniform distribution. If this works for you, you can safely discard the param_dist parameter. I will take a look at the error and fix it later.

Ok, thanks so much！ @bailud And I complie the code by adding -fcommon to makefile which is mentioned in (https://github.com/microsoft/dsb/pull/5/commits/42896f5647c2da79961d24f634843e603d699729)；It's really helpful for users who want to use this benchmark in Linux environment.

Hi! And I find that some parameters which work in original TPCH-DS seem to not work here, like "-scale";
When I run
./dsqgen -input mypath/dsb/query_templates_pg/multi_block_queries/templates.lst -output_dir mypath/dsb_workload/multi -streams 10 -directory mypath/dsb/query_templates_pg/multi_block_queries -dialect postgres -scale 1 -rngseed 997
I got
ERROR: Open failed on 'my_path/dsb/query_templates_pg/multi_block_queri1' my_path/dsb/query_templates_pg/multi_block_queri1: No such file or directory

Hi @EvagelineFEI, the error message indicates that there is some issue with the path of the files. It may be related to the previous issue. I will take a look over the weekend.

Hi @EvagelineFEI , I just realized that the binary you use is the one that generates the queries, not the data. The binary to generate the data is dsdgen. Could you double check and try dsdgen?

@EvagelineFEI I took another look at the command you use. Could you use -template with the template file name instead of using -input and see if that works?

commented

I will close this issue since this is due to the misuse of the commands.

@bailud Thanks so much! I ll double check
