Prior to Qlik he was responsible for BI transformation and delivery across a number of Financial Services organizations. This experience and extensive product knowledge enables some of our largest enterprise customers to succeed at unlocking business insight through Qlik. Steven leads the global Advanced Analytics team within Pre-Sales and through this role brings us this update.  In this blog, Steve recaps the last 8 months of Qlik's latest enhancement to Qlik Sense and QlikView: Advanced Analytics Integration (AAI). He also shares the details on what's new with AAI in the February 2018 release including a sample on how it works.

Take it away Steve!


8 Months of Advanced Analytics Integration

Last June when Qlik Sense was released, it contained one of the biggest changes to the engine since the second generation data indexing engine engine was released with the launch of Qlik Sense in 2015. The server-side extensions API, more commonly referred to as Advanced Analytics Integration (AAI) was made generally available, providing a way for calculations to be externalized from the engine on demand as part of the user’s session.

The capability and flexibility enabled developers to explore new use cases for their Qlik applications, and most importantly business users have more access to insights than ever before.


When we launched AAI, two open source connector projects were created. One for python and one for R. Supporting these two popular languages first, provided a way for users to connect to two of the most popular advanced analytics tools of choice. Since then, the R&D team has broadened Qlik's AAI projects by adding examples for C#, C++, GO and JAVA.


Over the last 8 months we have seen customers and partners deliver solutions using the out of the box sample R connector as well as create custom calculation engines to solve other calculation problems such as decryption and live data augmentation.

The next big milestone for AAI was the November 2017 release of QlikView, which brought the same AAI capabilities launched with Qlik Sense to QlikView. This gave QlikView customers a whole new set of opportunities for both old and new applications. The underlying technology for QlikView is the same as Qlik Sense, meaning you can share all the services already built with only a simple configuration step on your desktop or server. If you have not yet looked at how you can bring new a new perspective to your QlikView applications with Advanced Analytics Integration I will be presenting a session dedicated to AAI for QlikView at Qonnections 2018 (<- Customers and Partners sign up here), I hope to see some of you there.


The Qlik Community

As with many aspects of the Qlik product line, AAI’s success is made possible by the strong community who collaborate and share. The Qlik community space for advanced analytics integration is widely used and moving forward. This year we are planning to give it a facelift to make it easier to navigate and find information so more customers can make use of the technology in their businesses. If you have not yet got started with AAI or are experienced in the technology, do drop by and explore the resources available.


What’s new

This blog was written to coincide with the Qlik Sense February 2018 release, which is now generally available and includes the latest feature release for AAI which now supports whole table processing in the load script. A commonly requested feature is to be able to batch process algorithms for tasks such as model training and scoring. This was possible in a limited row by row capacity at launch, however with the new version we now support sending whole tables to and from the external calculation engine as a standard part of the application load script - made possible through a simple extension to the LOAD syntax.


So, how does this work?

When writing your application script there is now an extended syntax to the load statement, like the FROM or RESIDENT statements that have their specific uses. Qlik can now use the reserved statement, EXTENSION, to specify that the source of the loaded data table will be the result of an AAI function.


The following example calls an R script to score some input data using a table already loaded into the Qlik data model and returns a result:


 num(p,'##0.##') AS Predict_Score 
 R.ScriptEval(' … R Script Here … ',
 Rentals{RowID,Year,Month,Day,RentalCount,WeekDay,Holiday,Snow });

As you can see, the returned results are accessible to be processed using all the standard Qlik script functions providing a useful addition to the script syntax.

Where to Next?

There are lots of resources available to help you succeed with Advanced Analytics Integration, here are a few of the key links to explore:



  • This repository provides a server-side extension (SSE) protocol based on gRPC that allows you to extend the Qlik built-in expression library with functionality from external calculation engines. You can use external calculation engines in both load scripts and charts. In Qlik Sense and QlikView, you connect to these server-side extensions (SSEs) by defining analytic connections.
  • This repository provides a server-side extension (SSE) that allows you to extend the Qlik built-in expression library with functionality from R. You can use this in both load scripts and charts. In Qlik Sense and QlikView, you connect to this SSE R-plugin by defining an analytic connection.
  • The AAI Advanced Analytics Expression Builder is a Qlik Sense extension used to create advanced analytics expressions as master items and wrap these in to a pre-built visualization. These visualizations use native chart types and can be edited either as a master item or un-linked and customized.!/project/596f87f186a5cf7ec72e90e9

  • Qlik Sense extension which allows you to create charts to perform advanced analytics by simple drag and drop without complex scripting. This extension works on the top of the Advanced Analytics Integration (AAI) functionality with R.!/project/5979da222ef8975d99132f88
