How to run a huge data set?

Hello, Gözde,
 
Thank you for posting to our forum.
 
First of all, our team would like to provide you with some explanations on setting the data via the setReport() API call. We assume it may help to solve the issue.
Please follow the steps below: 
1) Create a report object with the data source specified:

var report = {
        dataSource: {
            filename: "https://cdn.flexmonster.com/data/data.csv"
        } 
    }

2) Call the setReport method with the report object as a parameter:

pivot.setReport(report); 

 
Here is the example for your reference: http://jsfiddle.net/flexmonster/L0n1r933/.
Please inform us if it helped.
 
Secondly, could you please let us know the size of your data? So we can provide you with the most relevant recommendations for your data source.
 
Looking forward to hearing from you.
 
Best regards,
Milena

Hi, Gözde,
 
Thank you for providing the file with the report.
 
Our team has investigated your report and found the cause of the issue. The JSON data specified in the data property of the dataSource object significantly increases the report size. As Flexmonster needs to process the report of that size, the component can give no response for some time.
 
Instead of the data, we suggest using the filename property - the URL to the file or the server-side script which generates data.
Please use the following code snippet for your reference: 

{
    dataSource: {
        /* Path to the local file or to the script which returns data */
        filename: "data.json"
    }
}

 
With this approach, the data is loaded separately from the report. Comparing to parsing the JSON from the report, this is a more optimized solution for big data. 
 
Let us know if our suggestion helped.
Waiting for your response.
 
Kind regards,
Milena
