# TPC-DS (2012)
Similar to the [Star Schema Benchmark (SSB)](star-schema.md), TPC-DS is based on [TPC-H](tpch.md), but it took the opposite route, i.e. it expanded the number of joins needed by storing the data in a complex snowflake schema (24 instead of 8 tables).
The data distribution is skewed (e.g. normal and Poisson distributions).
It includes 99 reporting and ad-hoc queries with random substitutions.
References
- [The Making of TPC-DS](https://dl.acm.org/doi/10.5555/1182635.1164217) (Nambiar), 2006
First, checkout the TPC-H repository and compile the data generator:
``` bash
$ git clone https://github.com/gregrahn/tpcds-kit.git
$ cd tpcds-kit/tools
$ make
```
Then, generate the data. Parameter `-scale` specifies the scale factor.
``` bash
$ ./dsdgen -scale 1
```
Then, generate the queries (use the same scale factor):
```bash
./dsqgen -DIRECTORY ../query_templates/ -INPUT ../query_templates/templates.lst -SCALE 1 # generates 99 queries in out/query_0.sql
```
Now create tables in ClickHouse.
You can either use the original table definitions in tools/tpcds.sql or "tuned" table definitions with properly defined primary key indexes and LowCardinality-type column types where it makes sense.

Then run the generated queries.
::::warning
TPC-DS makes heavy use of correlated subqueries which are at the time of writing (September 2024) not supported by ClickHouse ([issue #6697](https://github.com/ClickHouse/ClickHouse/issues/6697)).
As a result, many of below benchmark queries will fail with errors.
