| =========== | |
| This repo contains the code used for performance evaluation of polars. The benchmarks are TPC-standardised queries and data designed to test the performance of "real" workflows. | |
| From the [TPC website](https://www.tpc.org/tpch/): | |
| > TPC-H is a decision support benchmark. It consists of a suite of business-oriented ad hoc queries and concurrent data modifications. The queries and the data populating the database have been chosen to have broad industry-wide relevance. This benchmark illustrates decision support systems that examine large volumes of data, execute queries with a high degree of complexity, and give answers to critical business questions. | |
| ## Generating TPC-H Data | |
| ### Project setup | |
| ```shell | |
| # clone this repository | |
| git clone https://github.com/pola-rs/tpch.git | |
| cd tpch/tpch-dbgen | |
| # build tpch-dbgen | |
| make | |
| ``` | |
| Notes: | |
| - For MacOS, the above `make` command will result in an error while compiling like below, | |
| ```shell | |
| bm_utils.c:71:10: fatal error: 'malloc.h' file not found | |
| #include <malloc.h> | |
| ^~~~~~~~~~ | |
| 1 error generated. | |
| make: *** [bm_utils.o] Error 1 | |
| ``` | |
| To fix this, change the import statement `#include <malloc.h>` to `#include <sys/malloc.h>` in the files where error | |
| is reported (`bm_utils.c` and `varsub.c`) and then re-run the command `make`. | |
| ### Execute | |
| ```shell | |
| # change directory to the root of the repository | |
| cd ../ | |
| ./run.sh | |
| ``` | |
| This will do the following, | |
| - Create a new virtual environment with all required dependencies. | |
| - Generate data for benchmarks. | |
| - Run the benchmark suite. | |
