Re: Regarding issue #6510 - Mailing list pgadmin-hackers

Hi Hackers,

I am working on issue #6510, where the result grid slows down and sometimes hangs when large JSON or text data is present in a table column. Upon investigation, I found that this is due to rendering the entire JSON to the DOM. This causes slowness, especially with large datasets; for example, rendering a 15MB JSON object for preview purposes is unnecessary. I am proposing a solution where the result grid will render data up to a certain length. I have implemented these changes, and everything is working fine, resulting in a significant performance improvement. As you can see in the screenshot, the JSON data is 20MB, and on the result grid, we are displaying only 200 characters as it is only a preview. I am also considering making this maximum display length a user preference, named "Max column data display length," allowing them to customize how much data they want to see. Can you tell me what you think of this approach or if you have any suggestions?

Thanks,

Pravesh
