# Terabyte of Click Logs from Criteo
|
|
|
|
Download the data from http://labs.criteo.com/downloads/download-terabyte-click-logs/
|
|
|
|
Create a table to import the log to:
|
|
|
|
``` sql
|
|
CREATE TABLE criteo_log (
|
|
date Date,
|
|
clicked UInt8,
|

|
|
) ENGINE = Log;
|
|
```
|
|
|
|
Download the data:
|
|
|
|
``` bash
|
|
$ for i in {00..23}; do echo $i; zcat datasets/criteo/day_${i#0}.gz | sed -r 's/^/2000-01-'${i/00/24}'\t/' | clickhouse-client --host=example-perftest01j --query="INSERT INTO criteo_log FORMAT TabSeparated"; done
|
|
```
|
|
|
|
Create a table for the converted data:
|
|
|
|
``` sql
|
|

PARTITION BY toYYYYMM(date)
