Qlik Sense: How to enable handling and queuing of simultaneous identical requests
Article Number: 000094559 | Last Modified: 2020/01/31
Description
Improved HTTP connection handling and queuing of simultaneous identical requests For simultaneous and identical GET requests (based on path, query and headers), response time has been improved by grouping them in the HTTP connection handler queue, only executing one call per group and using the result of that call to respond to all the requests in that group. This results in significantly improved performance on a loaded system. It decreases the load on the service and shortens the response time for subsequent simultaneous, identical and time consuming requests. This change applies to any GET request and performance improvements are beneficial for all endpoints with that HTTP method.
