Implementing a virtualized list with react-window for 100k rows

Scenario

Context An admin panel must display a searchable list of 100,000 log entries without pagination. The Problem Rendering all rows simultaneously causes 15+ second initial load times and makes scrolling completely unusable. Constraints Use FixedSizeList from react-window to virtualize the row rendering. Integrate search filtering without disabling virtualization. Handle dynamic row heights if entries vary in size. Expected Deliverable A React virtualized list implementation using react-window that renders 100k rows performantly, with integrated search filtering and stable scroll behavior.
