How often should an application reload if it needs near real-time data from a SQL database?

For an application that requires near real-time data from a SQL database, it is most effective to perform reloads every 5 minutes. This frequency allows the application to retrieve and reflect the latest data quickly, making it suitable for scenarios where data changes rapidly and timely insights are crucial.

Reloading every 5 minutes ensures that users have access to data that is as current as possible, which is essential for decision-making processes that rely on near real-time information. This strategy minimizes the lag between data generation in the SQL database and data accessibility in your Qlik application, thereby enhancing the user experience and improving the relevance of the insights derived from the data.

In contrast, reloading every hour or every 15 minutes would not provide the necessary immediacy for applications needing up-to-the-minute accuracy, while a daily reload would be too infrequent to meet the needs of a near real-time environment.
