# OCR Queue System Improvements
|
||||||
|
|
||||||
|
This document describes the major improvements made to handle large-scale OCR processing of 100k+ files.
|
||||||
|
|
||||||
|
## Key Improvements
|
||||||
|
|
||||||
|
### 1. **Database-Backed Queue System**
|
||||||
|
- Replaced direct processing with persistent queue table
|
||||||
|
- Added retry mechanisms and failure tracking
|
||||||
|
- Implemented priority-based processing
|
||||||
|
- Added recovery for crashed workers
|
||||||
|
|
||||||
|
### 2. **Worker Pool Architecture**
|
||||||
|
- Dedicated OCR worker processes with concurrency control
|
||||||
|
- Configurable number of concurrent jobs
|
||||||
|
- Graceful shutdown and error handling
|
||||||
|
- Automatic stale job recovery
|
||||||
|
|
||||||
|
### 3. **Batch Processing Support**
|
||||||
|
- Dedicated CLI tool for bulk ingestion
|
||||||
|
- Processes files in configurable batches (default: 1000)
|
||||||
|
- Concurrent file I/O with semaphore limiting
|
||||||
|
- Progress monitoring and statistics
|
||||||
|
|
||||||
|
### 4. **Priority-Based Processing**
|
||||||
|
Priority levels based on file size:
|
||||||
|
- **Priority 10**: ≤ 1MB files (highest)
|
||||||
|
- **Priority 8**: 1-5MB files
|
||||||
|
- **Priority 6**: 5-10MB files
|
||||||
|
- **Priority 4**: 10-50MB files
|
||||||
|
- **Priority 2**: > 50MB files (lowest)
|
||||||
|
|
||||||
|
### 5. **Monitoring & Observability**
|
||||||
|
- Real-time queue statistics API
|
||||||
|
- Progress tracking and ETAs
|
||||||
|
- Failed job requeuing
|
||||||
|
- Automatic cleanup of old completed jobs
|
||||||
|
|
||||||
|
## Database Schema
|
||||||
|
|
||||||
|
### OCR Queue Table
|
||||||
|
```sql
|
||||||
|
CREATE TABLE ocr_queue (
|
||||||
|
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
|
||||||
|
document_id UUID REFERENCES documents(id) ON DELETE CASCADE,
|
||||||
|
status VARCHAR(20) DEFAULT 'pending',
|
||||||
|
priority INT DEFAULT 5,
|
||||||
|
attempts INT DEFAULT 0,
|
||||||
|
max_attempts INT DEFAULT 3,
|
||||||
|
created_at TIMESTAMPTZ DEFAULT NOW(),
|
||||||
|
started_at TIMESTAMPTZ,
|
||||||
|
completed_at TIMESTAMPTZ,
|
||||||
|
error_message TEXT,
|
||||||
|
worker_id VARCHAR(100),
|
||||||
|
processing_time_ms INT,
|
||||||
|
file_size BIGINT
|
||||||
|
);
|
||||||
|
```
|
||||||
|
|
||||||
|
### Document Status Tracking
|
||||||
|
- `ocr_status`: Current OCR processing status
|
||||||
|
- `ocr_error`: Error message if OCR failed
|
||||||
|
- `ocr_completed_at`: Timestamp when OCR completed
|
||||||
|
|
||||||
|
## API Endpoints
|
||||||
|
|
||||||
|
### Queue Status
|
||||||
|
```
|
||||||
|
GET /api/queue/stats
|
||||||
|
```
|
||||||
|
Returns:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"pending": 1500,
|
||||||
|
"processing": 8,
|
||||||
|
"failed": 12,
|
||||||
|
"completed_today": 5420,
|
||||||
|
"avg_wait_time_minutes": 3.2,
|
||||||
|
"oldest_pending_minutes": 15.7
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Requeue Failed Jobs
|
||||||
|
```
|
||||||
|
POST /api/queue/requeue-failed
|
||||||
|
```
|
||||||
|
Requeues all failed jobs that haven't exceeded max attempts.
|
||||||
|
|
||||||
|

||||||
|
|
||||||
|
### Batch Ingestion
|
||||||
|
```bash
|
||||||
|
# Ingest all files from a directory
|
||||||
|
cargo run --bin batch_ingest /path/to/files --user-id 00000000-0000-0000-0000-000000000000
|
||||||
|
|
||||||
|
# Ingest and monitor progress
|
||||||
|
cargo run --bin batch_ingest /path/to/files --user-id USER_ID --monitor
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
### Environment Variables
|
||||||
|
- `OCR_CONCURRENT_JOBS`: Number of concurrent OCR workers (default: 4)
|
||||||
|
- `OCR_TIMEOUT_SECONDS`: OCR processing timeout (default: 300)
|
||||||
|
- `QUEUE_BATCH_SIZE`: Batch size for processing (default: 1000)
|
||||||
|
- `MAX_CONCURRENT_IO`: Max concurrent file operations (default: 50)
|
||||||
|
|
||||||
|
### User Settings
|
||||||
|
Users can configure:
|
||||||
|
- `concurrent_ocr_jobs`: Max concurrent jobs for their documents
|
||||||
|
- `ocr_timeout_seconds`: Processing timeout
|
||||||
|
- `enable_background_ocr`: Enable/disable automatic OCR
|
||||||
|
|
||||||
|
## Performance Optimizations
|
||||||
|
|
||||||
|
### 1. **Memory Management**
|
||||||
|
- Streaming file reads for large files
|
||||||
|
- Configurable memory limits per worker
|
||||||
|
- Automatic cleanup of temporary data
|
||||||
|
|
||||||
|
### 2. **I/O Optimization**
|
||||||
|
- Batch database operations
|
||||||
|
- Connection pooling
|
||||||
|
- Concurrent file processing with limits
|
||||||
|
|
||||||
|
### 3. **Resource Control**
|
||||||
|
- CPU priority settings
|
||||||
|
- Memory limit enforcement
|
||||||
|
- Configurable worker counts
|
||||||
|
|
||||||
|
### 4. **Failure Handling**
|
||||||
|
- Exponential backoff for retries
|
||||||
|
- Separate failed job recovery
|
||||||
|
- Automatic stale job detection
|
||||||
|
|
||||||
|
## Monitoring & Maintenance
|
||||||
|
|
||||||
|
### Automatic Tasks
|
||||||
|
- **Stale Recovery**: Every 5 minutes, recover jobs stuck in processing
|
||||||
|
- **Cleanup**: Daily cleanup of completed jobs older than 7 days
|
||||||
|
- **Health Checks**: Worker health monitoring and restart
|
||||||
|
|
||||||
|
### Manual Operations
|
||||||
|
```sql
|
||||||
|
-- Check queue health
|
||||||
|
SELECT * FROM get_ocr_queue_stats();
|
||||||
|
|
||||||
|
-- Find problematic jobs
|
||||||
|
SELECT * FROM ocr_queue WHERE status = 'failed' ORDER BY created_at;
|
||||||
|
|
||||||
|
-- Requeue specific job
|
||||||
|
UPDATE ocr_queue SET status = 'pending', attempts = 0 WHERE id = 'job-id';
|
||||||
|
```
|
||||||
|
|
||||||
|
## Scalability Improvements
|
||||||
|
|
||||||
|
### For 100k+ Files:
|
||||||
|
1. **Horizontal Scaling**: Multiple worker instances across servers
|
||||||
|
2. **Database Optimization**: Partitioned queue tables by date
|
||||||
|
3. **Caching**: Redis cache for frequently accessed metadata
|
||||||
|
4. **Load Balancing**: Distribute workers across multiple machines
|
||||||
|
|
||||||
|
### Performance Metrics:
|
||||||
|
- **Throughput**: ~500-1000 files/hour per worker (depends on file size)
|
||||||
|
- **Memory Usage**: ~100MB per worker + file size
|
||||||
|
- **Database Load**: Optimized with proper indexing and batching
|
||||||
|
|
||||||
|
## Migration Guide
|
||||||
|
|
||||||
|
### From Old System:
|
||||||
|
1. Run database migration: `migrations/001_add_ocr_queue.sql`
|
||||||
|
2. Update application code to use queue endpoints
|
||||||
|
3. Monitor existing processing and let queue drain
|
||||||
|
4. Start new workers with queue system
|
||||||
|
|
||||||
|
### Zero-Downtime Migration:
|
||||||
|
1. Deploy new code with feature flag disabled
|
||||||
|
2. Run migration scripts
|
||||||
|
3. Enable queue processing gradually
|
||||||
|
4. Monitor and adjust worker counts as needed
