UI Lag While Scrolling Large Result Sets from ClickHouse #1219

What happened?

When querying a ClickHouse table that contains more than 500 columns, the database client UI becomes extremely laggy during scrolling after the initial page load.

The issue is consistently reproducible when the client loads the first 1000 rows of the dataset. Scrolling horizontally or vertically causes noticeable UI freezes and poor responsiveness.

Steps to reproduce

  1. Connect to a ClickHouse instance.
  2. Open a table containing more than 500 columns and 100K+ rows.
  3. Try scrolling through the UI.

Expected behavior

scrolling should be smooth
