tpcds-kit

The official TPC-DS tools can be found at tpc.org.

This version is based on v2.10.0 and has been modified to:

• Allow compilation under macOS (commit 2ec45c5)
• Address obvious query template bugs like
  • query22a: #31
  • query77a: #43
• Rename s_web_returns column wret_web_site_id to wret_web_page_id to match specification. See #22 & #42.

To see all modifications, diff the files in the master branch to the version branch. Eg: master vs v2.10.0.

Using the TPC-DS tools

Data generation

Data generation is done via dsdgen. See dsdgen -help for all options. If you do not run dsdgen from the tools/ directory then you will need to use the option -DISTRIBUTIONS /.../tpcds-kit/tools/tpcds.idx. The output directory (specified via the -DIR option) must exist prior to running dsdgen.

Query generation

Query generation is done via dsqgen. See dsqgen -help for all options.

The following command can be used to generate all 99 queries in numerical order (-QUALIFY) for the 10TB scale factor (-SCALE) using the Netezza dialect template (-DIALECT) with the output going to /tmp/query_0.sql (-OUTPUT_DIR).

dsqgen \
-DIRECTORY ../query_templates \
-INPUT ../query_templates/templates.lst \
-VERBOSE Y \
-QUALIFY Y \
-SCALE 10000 \
-DIALECT netezza \
-OUTPUT_DIR /tmp
