What is the purpose of Scan operation (scan($match, $count = 10000) in ReportController.php)?
What's the interval to run the scan operation and is it recommended to change the scan interval?
Most importantly, is it recommended to change the $count from 10000 to a less number (ex: 500)?

    Our patch resolves a critical issue in Redis log page, previously broken when dealing with large Redis datasets. By adjusting the scan value from 10,000 to 1,000, the patch optimizes log retrieval, ensuring faster load times and improved usability.
