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.

Data Generation and Import
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.
We stick as closely as possible to the rules of the TPC-H specification:
- Primary keys are created only for the columns mentioned in section 1.4.2.2 of the specification.
- Substitution parameters were replaced by the values for query validation in sections 2.1.x.4 of the specification.
- As per section 1.4.2.1, the table definitions do not use the optional
NOT NULLconstraints, even ifdbgengenerates them by default. The performance ofSELECTqueries in ClickHouse is not affected by the presence or absence ofNOT NULLconstraints. - As per section 1.3.1, we use ClickHouse's native datatypes (e.g.
Int32,String) to implement the abstract datatypes mentioned in the specification (e.g.Identifier,Variable text, size N). The only effect of this is better readability, the SQL-92 datatypes generated bydbgen(e.g.INTEGER,VARCHAR(40)) would also work in ClickHouse.
