Qlik Sense delivers intuitive platform solutions for self-service data visualization, guided analytics applications, embedded analytics, and reporting. It is a new player in the Business Intelligence (BI) tools world, with a high growth since 2013. It has connectors with Hadoop Database (Hive and Impala). Now it can be integrated with Apache Kylin. This article will guide you to connect Apache Kylin with Qlik Sense.

Install Kylin ODBC Driver

For the installation information, please refer to Kylin ODBC Driver.

Install Qlik Sense

For the installation of Qlik Sense, please visit Qlik Sense Desktop download.

Connection with Qlik Sense

After configuring your Local DSN and installing Qlik Sense successfully, you may go through the following steps to connect Apache Kylin with Qlik Sense.

  • Open Qlik Sense Desktop.

  • Input your Qlik account to log in, then the following dialog will pop up. Click Create New Application.

Create New Application

  • Specify a name for the new app.

Specify a unique name

  • There are two choices in the Application View. Please select the bottom Script Editor.

Select Script Editor

ODBC Connection

Configure Direct Query mode

Change the default scripts of “TimeFormat”, “DateFormat” and “TimestampFormat” to:

SET TimeFormat='h:mm:ss'; SET DateFormat='YYYY-MM-DD'; SET TimestampFormat='YYYY-MM-DD h:mm:ss[.fff]';

Given the Peta-byte scale Cube size in a usual Apache Kylin environment, we recommend user to use Direct Query mode in Qlik Sense and avoid importing data into Qlik Sense.

You are able to enable Direct Query mode by typing Direct Query in front of your query script in Script editor.

Below is the screenshot of such Direct Query script against kylin_sales_cube in Learn_kylin project.

Script

Once you defined such script, Qlik sense can generate SQL based on this script for your report.

It is recommended that you define Dimension and Measure corresponding to the Dimension and Measure in the Kylin Cube.

You may also be able to utilize Apache Kylin built-in functions by creating a Native expression, for example:

NATIVE('extract(month from PART_DT)')

The whole script has been posted for your reference.

Make sure to update LIB CONNECT TO 'kylin'; to the DSN you created.

SET ThousandSep=',';
SET DecimalSep='.';
SET MoneyThousandSep=',';
SET MoneyDecimalSep='.';
SET MoneyFormat='$#,##0.00;-$#,##0.00';
SET TimeFormat='h:mm:ss';
SET DateFormat='YYYY/MM/DD';
SET TimestampFormat='YYYY/MM/DD h:mm:ss[.fff]';
SET FirstWeekDay=6;
SET BrokenWeeks=1;
SET ReferenceDay=0;
SET FirstMonthOfYear=1;
SET CollationLocale='en-US';
SET CreateSearchIndexOnReload=1;
SET MonthNames='Jan;Feb;Mar;Apr;May;Jun;Jul;Aug;Sep;Oct;Nov;Dec';
SET LongMonthNames='January;February;March;April;May;June;July;August;September;October;November;December';
SET DayNames='Mon;Tue;Wed;Thu;Fri;Sat;Sun';
SET LongDayNames='Monday;Tuesday;Wednesday;Thursday;Friday;Saturday;Sunday';

Click Load Data on the upper right of the window, Qlik sense will send out inspection query to test the connection based on the script.

Load Data

Create a new report

On the top left menu open App Overview.

Open App Overview

Click Create new sheet on this page.

Create new sheet

Select the charts you need, then add dimension and measurement based on your requirements.

Select the required charts, dimension and measure

You will get your worksheet and the connection is complete. Your Apache Kylin data shows in Qlik Sense now.

View data in Qlik Sense

Please note that if you want the report to hit on Cube, you need to create the measure exactly as those are defined in the Cube. For the case of Kylin_sales_cube in Learn_kylin project. We use sum(price) as an example.
