Assessment
This issue has not been assessed yet.
Description
ReEditor becomes unresponsive/hangs when loading or editing large SQL content containing around 50,000 lines.
Steps to reproduce:
- Open the editor.
- Load or paste SQL content containing approximately 50,000 lines.
- Try to edit the content, scroll through the editor, or perform normal editor actions.
- Observe the editor response.
Actual result:
The ReEditor becomes slow and may hang/become unresponsive while processing the large content.
Expected result:
The editor should remain responsive and provide smooth editing and scrolling even with large SQL content.
Impact:
This causes a poor user experience when working with large SQL scripts and indicates a performance/scalability issue in the editor.
Request:
Investigate and optimize ReEditor performance for large documents, particularly around the 50,000line range. Reduce UI freezes/hangs and ensure editor operations remain responsive with large SQL content.
