TPC-H (1999)
A popular benchmark which models the internal data warehouse of a wholesale supplier. The data is stored into a 3rd normal form representation, requiring lots of joins at query runtime. Despite its age and its unrealistic assumption that the data is uniformly and independently distributed, TPC-H remains the most popular OLAP benchmark to date.

First, checkout the TPC-H repository and compile the data generator:
git clone https://github.com/gregrahn/tpch-kit.git
cd tpch-kit/dbgen
make
Then, generate the data. Parameter -s specifies the scale factor. For example, with -s 100, 600 million rows are generated for table 'lineitem'.
./dbgen -s 100
Now create tables in ClickHouse:

The data can be imported as follows:
clickhouse-client --format_csv_delimiter '|' --query "INSERT INTO nation FORMAT CSV" < nation.tbl
clickhouse-client --format_csv_delimiter '|' --query "INSERT INTO region FORMAT CSV" < region.tbl
clickhouse-client --format_csv_delimiter '|' --query "INSERT INTO part FORMAT CSV" < part.tbl

clickhouse-client --format_csv_delimiter '|' --query "INSERT INTO orders FORMAT CSV" < orders.tbl
clickhouse-client --format_csv_delimiter '|' --query "INSERT INTO lineitem FORMAT CSV" < lineitem.tbl
The queries are generated by ./qgen -s <scaling_factor>. Example queries for s = 100:
::::warning TPC-H makes heavy use of correlated subqueries which are at the time of writing (September 2024) not supported by ClickHouse (issue #6697). As a result, many of below benchmark queries will fail with errors. ::::
