    Query on QlikSense Reload Task Optimization: Cores, VCPUs, and Threads

    Hi All,

    I am writing to seek clarification on the optimal configuration for reloading Qlik Sense apps. According to best practices, it is recommended to set the maximum number of concurrent reloads to the number of cores minus 2. For example, on a system with 16 cores, the ideal setting would be 14 concurrent reloads. Article - https://customerportal.qlik.com/article/Concurrent-Reload-Settings-in-Qlik-Sense-Enterprise

    To better understand how to optimize our server configuration, I have the following questions:

    • What is the relationship between cores, VCPUs, and threads in Qlik Sense, and how do they impact reload tasks?
    • Do I need to increase the number of cores or VCPUs to accommodate more reload tasks, or is one more beneficial than the other?
    • What are the benefits and drawbacks of having more cores, VCPUs, or threads in terms of reload speed and overall system performance?
    • Specifically, does increasing the number of cores or VCPUs lead to faster reload times, or are there diminishing returns?
    • Are there any recommendations for configuring threads, and how do they interact with cores and VCPUs?

    I would appreciate it if you could provide a clear explanation or point me to relevant documentation.

    Thanks in advance.

    Hi team

    I am able to obtain the JSON response as part of an API GET request via postman.
    I am using the same headers in tREST as well as tRESTClient components, I am getting the status code as 200 but the body, I am not getting as JSON format instead I am getting in some decoded format or something.

    How to resolve this issue and how to obtain the response in exact JSON format.

    Thanks

    Hi,

    I need to perform a POST call with a PDF file attached.

    With Postman it works without any issues using form-data.

    bonacq_0-1776177213765.png

    The only component that seems suitable for my case in Talend 8.0.1 is tHTTPClient, but I haven’t found the correct configuration.
     
    Initially, I tried the most straightforward approach:

    bonacq_1-1776177301640.png

    and the attachment definition:

    bonacq_2-1776177345268.png

    but I get: HTTP Query 'http://.../uploadMainDocument' : '400 Bad Request'

    Using x-www-form-urlencoded, I add the file path among the body parameters (and remove the attachment), but I get: HTTP Query 'http://.../ws/uploadMainDocument' : '415 Unsupported Media Type'

    Has anyone encountered similar situations?

    Thanks
