### PR #2600: feat: improve table performance with virtualization

- **Author**: developer1
- **Created**: 2024-07-15T10:00:00Z
- **Status**: closed (merged)
- **URL**: https://github.com/ydb-platform/ydb-embedded-ui/pull/2600
- **Valuable comments**: 4

#### Comment 1: performance (implemented)

**Author**: reviewer1
**Created**: 2024-07-16T09:00:00Z
**File**: `src/components/Table/TableRow.tsx` (line 45)

**Comment**:
```
Great performance improvement! Consider using React.memo for the TableRow component to avoid unnecessary re-renders. Also, you might want to implement shouldComponentUpdate for class components.
```

**Discussion**:
1. **reviewer1**: Great performance improvement! Consider using React.memo for the TableRow component to avoid unnecessary re-renders. Also, you might want to implement shouldComponentUpdate for class components.
2. **developer1**: Good suggestion! I'll add React.memo to prevent unnecessary re-renders. Updated the component with proper memoization.

#### Comment 3: performance (likely_implemented)

**Created**: 2024-07-17T10:15:00Z
**File**: `src/components/VirtualTable/VirtualTable.tsx` (line 28)

**Comment**:
```
The virtualization looks good, but have you considered using react-window instead of react-virtualized? It has better performance and smaller bundle size. Also consider implementing proper error boundaries.
```

**Discussion**:
1. **reviewer2**: The virtualization looks good, but have you considered using react-window instead of react-virtualized? It has better performance and smaller bundle size. Also consider implementing proper error bound...
2. **developer1**: I looked into react-window but decided to stick with react-virtualized for consistency. We can migrate later. Added error boundaries as suggested.

Nice catch on the memory leak! Make sure to cleanup the monaco editor instance in the useEffect cleanup function. Also consider using AbortController for async operations.

# Usage Instructions for PR Comment Analysis

## Overview
This project contains automated scripts to analyze pull request comments and identify valuable feedback patterns for code quality improvement.

## Files
- `analyze-pr-comments.js` - Core analysis logic and comment classification
- `run-pr-analysis.js` - Main script that fetches data and generates reports
- `PR_ANALYSIS.md` - Generated analysis report (created when scripts run)

## Usage

### Prerequisites
- Node.js installed
- GitHub CLI (`gh`) installed and authenticated (optional, will use mock data if not available)

### Running the Analysis

```bash
# Run the complete analysis
node run-pr-analysis.js

# Or run the core logic tests
node analyze-pr-comments.js
```

### Configuration
The script analyzes PRs from the last 3 months by default. To change this:
1. Edit the `threeMonthsAgo.setMonth()` calculation in `analyze-pr-comments.js`
2. Or modify the `dateFilter` variable

### Output
The script generates `PR_ANALYSIS.md` with:
- Summary statistics by suggestion type and implementation status
- Detailed analysis of each valuable comment
- Discussion threads and outcomes
- Code context and file references

## Comment Classification
Comments are classified as valuable if they contain:
- Code quality suggestions (refactoring, optimization, etc.)
- Security or performance concerns
- Testing or documentation improvements
- Architecture or design discussions
- Technical implementation feedback

## Implementation Status Detection
The script automatically determines if suggestions were:
- **Implemented**: Based on follow-up comments indicating resolution
- **Rejected**: Based on disagreement or explicit rejection
- **Pending**: Still under discussion or unresolved
- **Likely Implemented**: PR was merged without explicit resolution
- **Abandoned**: PR was closed without merging
