Design of Qlikview In-Memory Engine

[Anonymous]

Hi,

How does qlikview store data into memory, do they create a windows service or process on the server

and then feed of this in the front - end.

I am just trying to get a better idea of how Qlikview actually works.

Kind regards

There are couple of Windows based services that QlikView runs to manage its tasks, including loading data, storing and load balancing. Please find couple of service and brief description of what each services does :

QlikView Directory Service Connector :

Keeps track of all the users through the selected Directory Services.

QlikView Distribution Service :

The service that is responsible for the reload, distribution and reduction of the QlikView files.

QlikView Management Service :

Hosts the Management consoles and sends settings to the other services.

QlikView Server :

Hosts the QlikView files and allows users to access them through different clients.

QlikView Webserver:

The web server for the AccessPoint and the AJAX pages. Also responsible for load balancing the QVS.

You can go to (on Windows Server) Admin tools -> Services (Sort by service names and look for all services that starts with Qlik) -> Right click on each service -> Properties. You can find a brief description of each service there.

I hope this helps!
