# Brown University Benchmark
|
|
|
|
`MgBench` is a new analytical benchmark for machine-generated log data, [Andrew Crotty](http://cs.brown.edu/people/acrotty/).
|
|
|
|
Download the data:
|
|
```
|
|
wget https://datasets.clickhouse.tech/mgbench{1..3}.csv.xz
|

|
Unpack the data:
|
|
```
|
|
xz -v -d mgbench{1..3}.csv.xz
|
|
```
|
|
