Well, should I use it like this? [Improvement-16947][UI] Task instance log details should always stay at the bottom |
Add a button that allows the user to manually control whether to scroll to the bottom, without forcing automatic scrolling. Would that work? |

If we set to autoScrollToBottom to true by default. We should increase batch query log line num to 100000. This can significantly reduce the number of requests and improve the user experience.

Thanks for the suggestion! In normal cases, a limit of 1000 is sufficient for most scenarios. The GIF I provided was an exceptional example to demonstrate the auto-scroll-to-bottom functionality, but it doesn't reflect the typical usage. Therefore, I believe keeping the limit at 1000 is appropriate for now. If we encounter performance issues or higher demand in the future, we can revisit this setting.

In the production environment, 1000 is not enough for automatic refresh. It will cause great performance pressure on both frontend and backend. And we should avoid repeated execution and set a delay for it.
