+DataJuicer now includes an intelligent auto-configuration system that automatically determines optimal partition sizes based on your data characteristics: + +#### **How It Works** + +1. **Modality Detection**: Analyzes your dataset to detect the primary modality (text, image, audio, video, multimodal) +2. **Dataset Analysis**: Examines sample characteristics (text length, media counts, file sizes) +3. **Pipeline Complexity**: Considers the complexity of your processing operations +4. **Resource Optimization**: Adjusts partition sizes for optimal memory usage and fault tolerance + +#### **Modality-Specific Optimizations** + +| Modality | Default Size | Max Size | Memory Multiplier | Use Case | +|----------|--------------|----------|-------------------|----------| +| **Text** | 200 samples | 1000 | 1.0x | Efficient processing, low memory | +| **Image** | 50 samples | 200 | 5.0x | Moderate memory, image processing | +| **Audio** | 30 samples | 100 | 8.0x | High memory, audio processing | +| **Video** | 10 samples | 50 | 20.0x | Very high memory, complex processing | +| **Multimodal** | 20 samples | 100 | 10.0x | Multiple modalities, moderate complexity | + +#### **Enable Auto-Configuration** + +```yaml +partition: + auto_configure: true # Enable automatic optimization + # Manual settings are ignored when auto_configure is true + size: 200 + max_size_mb: 32 +``` + +#### **Manual Override** + +```yaml +partition: + auto_configure: false # Disable auto-configuration + size: 100 # Use your own partition size + max_size_mb: 64 +``` + +## 📊 Partition Sizing Guidelines + +### **Why Smaller Partitions Are Better** + +**Fault Tolerance**: Smaller partitions mean smaller units of failure. If a partition fails, you lose less work. + +**Recovery Speed**: Failed partitions can be retried faster, reducing overall job time. + +**Progress Visibility**: More granular progress tracking and faster feedback. + +**Memory Efficiency**: Lower memory usage per partition, better for resource-constrained environments. + +**Debugging**: Easier to isolate and debug issues in smaller chunks. + +### **Partition Size Recommendations** + +| Use Case | Partition Size | When to Use | +|----------|---------------|-------------| +| **Debugging** | 50-100 samples | Quick iterations, testing, small datasets | +| **Production** ⭐ | 100-300 samples | Most use cases, good balance | +| **Large Datasets** | 300-500 samples | Stable processing, large datasets | +| **Very Large** | 500+ samples | Only when failure risk is minimal | + +### **Factors to Consider** + +- **Dataset Size**: Larger datasets can use larger partitions +- **Processing Complexity**: Complex operations benefit from smaller partitions +- **Failure Rate**: Higher failure rates need smaller partitions +- **Memory Constraints**: Limited memory requires smaller partitions +- **Time Sensitivity**: Faster feedback needs smaller partitions + +## 🔧 Implementation Details + +### Core Components + +1. **`EventLoggingMixin`** (`data_juicer/core/executor/event_logging_mixin.py`) + - Provides event logging capabilities to executors + - Manages job-specific directories and flexible storage + - Handles job summary creation and validation + - Implements Spark-style event logging schema + +2. **`PartitionedRayExecutor`** (`data_juicer/core/executor/ray_executor_partitioned.py`) + - Extends Ray executor with partitioning and fault tolerance + - Implements configurable checkpointing strategies + - Integrates with EventLoggingMixin for comprehensive logging + - Handles job resumption from checkpoints + +3. **Configuration Integration** (`data_juicer/config/config.py`) + - Added command-line arguments for job management + - Added checkpointing configuration options + - Added flexible storage path configuration + +### Event Types +- `JOB_START`, `JOB_COMPLETE`, `JOB_FAILED` +- `PARTITION_START`, `PARTITION_COMPLETE`, `PARTITION_FAILED` +- `OP_START`, `OP_COMPLETE`, `OP_FAILED` +- `CHECKPOINT_SAVE`, `CHECKPOINT_LOAD` +- `PROCESSING_START`, `PROCESSING_COMPLETE`, `PROCESSING_ERROR` +- `RESOURCE_USAGE`, `PERFORMANCE_METRIC` +- `WARNING`, `INFO`, `DEBUG` + +## 🎯 Use Cases + +### 1. Large Dataset Processing +- Process datasets that are too large for memory +- Automatic partitioning with fault tolerance +- Resume processing after failures + +### 2.

Research and Development +- Iterative development with checkpoint resumption +- Detailed event logging for analysis +- Configurable checkpointing for different scenarios + +## 🔍 Troubleshooting + +### Common Issues + +1. **Job resumption fails** + - Check if job summary exists: `ls -la ./outputs/{work_dir}/{job_id}/job_summary.json` + - Verify checkpoint files exist: `ls -la /tmp/large_checkpoints/{job_id}/` + +2. **Event logs not found** + - Check flexible storage paths: `ls -la /tmp/fast_event_logs/{job_id}/` + - Verify event logging is enabled in config + +3. **Checkpointing not working** + - Verify checkpoint strategy in config + - Check if checkpoint directory is writable + - Ensure checkpoint.enabled is true + +4. **Performance issues** + - Adjust partition size based on available memory + - Consider different checkpoint strategies + - Use appropriate storage formats (parquet for large datasets) + +### Debug Commands +```bash +# Check Ray cluster status +ray status + +# View Ray dashboard +open http://localhost:8265 + +# Check DataJuicer logs +tail -f /tmp/fast_event_logs/{job_id}/event_logs/events.log +``` + +## 📊 Understanding Intermediate Data + +### What is Intermediate Data? + +Intermediate data refers to temporary results generated during the processing pipeline that exist between operations and before the final output. In DataJuicer's partitioned processing, this includes: + +1. **Partition-level intermediate data**: Results after each operation within a partition +2. **Operation-level intermediate data**: Data that exists between operations (e.g., after `clean_links_mapper` but before `whitespace_normalization_mapper`) +3. **Checkpoint intermediate data**: Temporary files created during checkpointing + +### When to Preserve Intermediate Data + +**Enable `preserve_intermediate_data: true` when you need:** +- **Debugging**: Inspect what the data looks like after each operation +- **Resumption**: If a job fails, see exactly where it failed and what the data looked like +- **Analysis**: Understand how each operation transforms the data +- **Development**: Iterate on processing pipelines with detailed inspection + +**Disable `preserve_intermediate_data: false` when you want:** +- **Performance**: Faster processing with less disk I/O +- **Storage efficiency**: Reduced disk space usage +- **Production**: Clean processing without temporary file accumulation + +### Example Directory Structure with Intermediate Data + +``` +{job_dir}/intermediate/ +├── partition_000000/ +│ ├──

logs +events = job_utils.load_event_logs() + +# Create processing snapshot +snapshot = create_snapshot("./outputs/job_20250809_040053_a001de") +``` + +### Event Analysis + +The system tracks various event types: + +- **Job Events**: `job_start`, `job_complete` +- **Partition Events**: `partition_creation_start`, `partition_creation_complete`, `partition_start`, `partition_complete`, `partition_failed` +- **Operation Events**: `op_start`, `op_complete`, `op_failed` +- **Checkpoint Events**: `checkpoint_save` +- **DAG Events**: `dag_build_start`, `dag_build_complete`, `dag_execution_plan_saved` + +## Best Practices + +### 1. Enable Resource Optimization + +Always enable resource optimization for production workloads: + +```yaml +resource_optimization: + auto_configure: true +``` + +### 2. Monitor Job Progress + +Use the snapshot utility to monitor long-running jobs: + +```bash +# Check job status +python -m data_juicer.utils.job.snapshot /path/to/job/directory + +# Get detailed analysis +python -m data_juicer.utils.job.snapshot /path/to/job/directory --human-readable +``` + +### 3. Configure Logging + +Set appropriate log rotation and retention: + +```python +setup_logger( + save_dir="./outputs", + max_log_size_mb=100, + backup_count=5 +) +``` + +### 4. Use Checkpointing + +Enable checkpointing for long-running jobs: + +```yaml +checkpoint: + enabled: true + strategy: "every_op" # or "every_partition", "every_n_ops" +``` + +### 5. Monitor Resource Usage + +The snapshot utility provides detailed resource utilization information: + +- Partition-level progress and timing +- Operation-level performance metrics +- Checkpoint coverage and resumability +- Overall job efficiency statistics + +## Integration Examples + +### Automation Script + +```python +import json +import subprocess +from pathlib import Path + +def monitor_job(job_dir: str): + """Monitor a Data-Juicer job and return status.""" + result = subprocess.run([ + "python", "-m", "data_juicer.utils.job.snapshot", job_dir + ], capture_output=True, text=True) + + if result.returncode == 0: + snapshot = json.loads(result.stdout) + return { + "status": snapshot["overall_status"], + "progress": snapshot["overall_progress"]["overall_percentage"], + "duration": snapshot["timing"]["duration_formatted"], + "resumable": snapshot["checkpointing"]["resumable"] + } + else: + return {"error": result.stderr} + +# Usage +status = monitor_job("./outputs/job_20250809_040053_a001de") +print(f"Job Status: {status['status']}, Progress: {status['progress']:.1f}%") +``` + +### Dashboard Integration + +The JSON output format makes it easy to integrate with monitoring dashboards: + +```python +def get_job_metrics(job_dir: str): + """Extract key metrics for dashboard display.""" + snapshot = create_snapshot(job_dir) + + return { + "job_id": snapshot.job_id, + "status": snapshot.overall_status.value, + "progress": { + "partitions": f"{snapshot.completed_partitions}/{snapshot.total_partitions}", + "operations": f"{snapshot.completed_operations}/{snapshot.total_operations}" + }, + "timing": { + "duration": snapshot.total_duration, + "start_time": snapshot.job_start_time + }, + "checkpointing": { + "resumable": snapshot.resumable, + "strategy": snapshot.checkpoint_strategy + } + } +``` + +## Troubleshooting + +### Common Issues + +1. **Job Not Starting**: Check resource availability and configuration +2. **Slow Performance**: Enable resource optimization and check partition sizes +3. **Memory Issues**: Reduce partition size or enable checkpointing +4. **Log File Growth**: Configure log rotation and retention policies + +### Debug Commands + +```bash +# Check job status +python -m data_juicer.utils.job.snapshot /path/to/job + +# Analyze events +python -c "import json; events = [json.loads(line) for line in open('/path/to/job/events.jsonl')]; print(f'Total events: {len(events)}')" + +# Check resource usage +python -c "from data_juicer.core.executor.partition_size_optimizer import ResourceDetector; print(ResourceDetector.detect_local_resources())" +``` + +## API Reference + +### ProcessingSnapshotAnalyzer + +```python +from data_juicer.utils.job.snapshot import ProcessingSnapshotAnalyzer + +analyzer = ProcessingSnapshotAnalyzer(job_dir) +snapshot = analyzer.generate_snapshot() +json_data = analyzer.to_json_dict(snapshot) +``` + +### ResourceDetector +
