 # WARC Cache and Download Module
 
-```{eval-rst}
-.. automodule:: owilix.core.tasks.warc
-   :members:
-   :undoc-members:
-   :show-inheritance:
+The WARC module provides high-performance downloading and caching of WARC (Web ARChive) files from distributed S3 storage, with support for pre-signed URLs, batch operations, and resume capabilities.
+
+## Overview
+
+The WARC download system supports two access methods:
+
+1. **Pre-signed URLs** (default, recommended): Secure, time-limited URLs obtained from OWS Dashboard API
+2. **Direct S3 credentials**: Traditional access using AWS-style credentials
+
+Pre-signed URLs eliminate the need to store and manage individual S3 credentials for multiple endpoints (IT4I, LRZ, CSC), providing centralized authentication via a single token.
+
+## Quick Start
+
+### Basic Usage with Pre-signed URLs
+
+```bash
+# Set your access token (obtain from OWS Dashboard)
+export OWI_WARC_ACCESS_TOKEN="your-token-here"
+
+# Or source the environment file
+source .env-rc
+
+# Download WARC files using pre-signed URLs (default)
+owi query warc --remote "lrz:latest" --warc-config warc-config.json
 ```
 
-# Main Processing Function
+### Configuration File
 
-Screenshot of the warc module usage:
+Create `warc-config.json`:

-## WARC Download function (used as OWILIX query subcommand)
+## Authentication
 
-```{eval-rst}
-.. autofunction:: owilix.core.tasks.warc.query_warc.warc
+### Token Priority (for Pre-signed URLs)
+
+Tokens are loaded in the following priority order:
+
+1. **CLI Parameter**: `--warc-token "token-value"`
+2. **Environment Variable**: `OWI_WARC_ACCESS_TOKEN`
+3. **Token File**: `~/.s3_access_token`
+
+### Using .env-rc File
+
+```bash
+# .env-rc file contents
+export OWI_WARC_ACCESS_TOKEN="your-dashboard-api-token"
+
+# Source it before running
+source .env-rc

+### Source Configuration Fields
 
-```{eval-rst}
-.. autoclass:: owilix.core.tasks.warc.query_warc.ZMQStreamingWARCProcessor
-   :members:
-   :special-members: __init__
+- **key** (required): Instance identifier (e.g., "lrz", "it4i", "csc")
+- **use_presign** (optional, default: true): Enable pre-signed URL mode for this source
+- **presign_api_url** (optional, default: "https://dashboard.ows.eu/api"): Pre-sign API endpoint
+- **prefix_mapping** (required): Path prefix mappings for URL transformation
+- **fsspec_type** (required): Filesystem type (usually "s3")
+- **config** (optional): Fallback S3 credentials if pre-sign fails
+
+### Mixed Mode Operation
+
+You can configure some sources to use pre-signed URLs and others to use direct credentials:
+
+```json
+{
+  "sources": [
+    {
+      "key": "lrz",
+      "use_presign": true
+    },
+    {
+      "key": "local-s3",
+      "use_presign": false,
+      "config": {
+        "key": "access-key",
+        "secret": "secret-key"
+      }
+    }
+  ]
+}
+```
+
+## Performance Optimization
+
+### Batch Operations
+
+For high-volume downloads, the system automatically uses batch operations:
+
+- **URL Caching**: Downloaded URLs are cached for 55 minutes (URLs expire after 1 hour)
+- **Batch Fetching**: Multiple URLs fetched in single API call
+- **Background Refresh**: URLs automatically refreshed 5 minutes before expiration
+- **LRU Eviction**: Cache limited to 10,000 entries with LRU eviction
+
+### Cache Statistics
+
+When verbose mode is enabled (`--verbose`), cache statistics are displayed on completion:
+
+```
+📊 Batch manager stats: 95.3% hit rate, 127 fetched, 23 refreshed
+```
+
+- **Hit Rate**: Percentage of cache hits vs misses
+- **Fetched**: Total URLs fetched from API
+- **Refreshed**: URLs automatically refreshed before expiration
+
+### Performance Tuning
+
+```bash
+# Adjust worker threads for parallelism
+owi query warc --remote "lrz:latest" \
+  --warc-config config.json \
+  --max-workers 20
+
+# Adjust batch sizes
+owi query warc --remote "lrz:latest" \
+  --warc-config config.json \
+  --batch-size 100 \
+  --pq-batch 5
+```
+
+## CLI Reference
+
+### Query WARC Command
+
+```bash
+owi query warc [OPTIONS]
+```
+
+#### Options
+
+- `--remote`, `-R`: Remote dataset specifier (e.g., "lrz:latest")
+- `--local`, `-L`: Local dataset specifier
+- `--where`, `-w`: SQL WHERE clause for filtering
+- `--limit`, `-l`: Maximum number of records to process
+- `--warc-config`: Path to WARC configuration file
+- `--warc-token`: Access token for pre-signed URLs (overrides env var)
+- `--use-presign` / `--no-presign`: Enable/disable pre-signed URL mode (default: enabled)
+- `--output`, `-o`: Output directory or log path
+- `--batch-size`: Rows per batch (default: 100)
+- `--pq-batch`: Parquet files per batch (default: 1)
+- `--max-workers`: Number of worker threads (default: 10)
+- `--verbose`: Enable verbose output
+- `--job`: Job name for logging
+
+## Architecture
+
+### Components
+
+1. **PresignClient**: API client for obtaining pre-signed URLs
+   - Single and batch URL fetching
+   - Retry logic with exponential backoff
+   - Token loading from multiple sources
+
+2. **BatchPresignManager**: High-performance URL caching
+   - Thread-safe LRU cache
+   - Background refresh before expiration
+   - Statistics tracking
+
+3. **HighPerformanceFileProcessor**: WARC file processing
+   - Pre-signed URL downloads with fallback to S3
+   - Per-thread destination management
+   - Detailed timing and bandwidth metrics
+
+4. **ZMQStreamingWARCProcessor**: Message queue architecture
+   - ZeroMQ-based task distribution
+   - Automatic back-pressure control
+   - Per-datacenter progress tracking
+
+### Data Flow
+
+```
+SQL Query → WARCTasks → RecordAggregator → FileJobs → Workers → WARC Files
+              ↓                                          ↓
+         Pre-fetch URLs                          Download via cached URLs
+              ↓                                          ↓
+         BatchManager Cache ← Background Refresh ← Expiration Monitor
+```
+
+## Error Handling
+
+### Automatic Fallback
+
+When pre-signed URL access fails, the system automatically falls back to direct S3 credentials:
+
+```
+⚠ Pre-sign failed, falling back to direct S3 for file.warc.gz
+```
+
+### Common Issues
+
+**Token Authentication Errors:**
+```bash
+# Check token is set
+echo $OWI_WARC_ACCESS_TOKEN
+
+# Verify token works
+curl -H "Authorization: Bearer $OWI_WARC_ACCESS_TOKEN" \
+  https://dashboard.ows.eu/api/s3/download-url
+```
+
+**Configuration Errors:**
+```bash
+# Validate JSON syntax
+python -m json.tool warc-config.json
+
+# Check paths and permissions
+ls -la /path/to/output
+```
+
+**Network Issues:**
+```bash
+# Test API connectivity
+curl -v https://dashboard.ows.eu/api/health
+
+# Check S3 endpoint connectivity
+curl -v https://vm-138-246-238-92.cloud.mwn.de:9000
 ```
 
-## Per-Thread Destination System
+## Advanced Features
 
-The core innovation is the per-thread destination architecture:
+### Resume Capability
+
+Resume interrupted downloads using job logs:
+
+```bash
+# First run (interrupted)
+owi query warc --remote "lrz:latest" \
+  --warc-config config.json \
+  --output ./output
+
+# Resume from where it left off
+owi query warc --remote "lrz:latest" \
+  --warc-config config.json \
+  --output ./output \
+  --resume
+```
+
+### Progress Monitoring
+
+The system displays real-time progress with per-datacenter statistics:
+
+```
+Per-Datacenter Progress
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+Datacenter  Progress        Q    ✓    ✗    Bandwidth    Rate

+## Migration Guide
+
+### From Direct S3 to Pre-signed URLs
+
+1. **Obtain Access Token**:
+   - Register at OWS Dashboard
+   - Generate API token
+   - Store in `~/.s3_access_token` or set `OWI_WARC_ACCESS_TOKEN`
+
+2. **Update Configuration**:
+   ```json
+   {
+     "sources": [{
+       "key": "lrz",
+       "use_presign": true,  // Add this
+       "presign_api_url": "https://dashboard.ows.eu/api",  // Add this
+       // Keep existing credentials as fallback
+       "config": { ... }
+     }]
+   }
+   ```
+
+3. **Test**:
+   ```bash
+   # Test with small limit first
+   owi query warc --remote "lrz:latest" \
+     --warc-config config.json \
+     --limit 10 \
+     --verbose
+   ```
+
+4. **Production Use**:
+   ```bash
+   # Run full download
+   owi query warc --remote "lrz:latest" \
+     --warc-config config.json
+   ```
+
+### Gradual Migration
+
+Migrate one datacenter at a time using mixed mode:
+
+```json
+{
+  "sources": [
+    {"key": "lrz", "use_presign": true},   // Migrated
+    {"key": "it4i", "use_presign": false}, // Not yet migrated
+    {"key": "csc", "use_presign": false}   // Not yet migrated
+  ]
+}
 ```
 
+## Security Best Practices
 
-## File Processing
+1. **Token Storage**:
+   - Never commit tokens to version control
+   - Use environment variables or secure token files
+   - Rotate tokens regularly
 
-### File Processor
+2. **Token Permissions**:
+   - Request minimum required permissions from Dashboard
+   - Use separate tokens for different environments (dev/prod)
 
-```{eval-rst}
-.. autoclass:: owilix.core.tasks.warc.query_warc.HighPerformanceFileProcessor
-   :members:
+3. **Network Security**:
+   - Always use HTTPS endpoints
+   - Verify SSL certificates
+   - Use VPN when accessing sensitive datacenters
+
+4. **Audit Logging**:
+   - Enable verbose mode for security audits
+   - Review job logs regularly
+   - Monitor cache hit rates for anomalies
+
+## Troubleshooting
+
+### High Cache Miss Rate
+
+If cache hit rate is low (<80%), check:
+
+1. **URL Expiration**: Default 1-hour URLs may expire for long-running jobs
+2. **Cache Size**: Increase `max_cache_size` in BatchPresignManager
+3. **Batch Size**: Increase `--batch-size` to improve URL reuse
+
+### Slow Performance
+
+1. **Increase Workers**: `--max-workers 20`
+2. **Adjust Batch Sizes**: `--batch-size 200 --pq-batch 10`
+3. **Check Network**: Test S3 endpoint latency
+4. **Review Datacenter Stats**: Identify slow datacenters
+
+### Authentication Failures
+
+1. **Token Expiration**: Regenerate token from Dashboard
+2. **Token Format**: Ensure no extra whitespace or newlines
+3. **API Endpoint**: Verify `presign_api_url` is correct
+4. **Network Access**: Test API connectivity
+
+## Examples
+
+### Basic Example
+
+```bash
+# Simple download with pre-signed URLs
+export OWI_WARC_ACCESS_TOKEN="your-token"
+owi query warc \
+  --remote "lrz:latest" \
+  --warc-config config.json \
+  --output ./warc-cache
+```
+
+### High-Volume Example
+
+```bash
+# Optimized for high-volume processing
+owi query warc \
+  --remote "lrz:latest" \
+  --warc-config config.json \
+  --output ./warc-cache \
+  --max-workers 30 \
+  --batch-size 200 \
+  --pq-batch 10 \
+  --verbose
+```
+
+### Filtered Download
+
+```bash
+# Download only specific URLs
+owi query warc \
+  --remote "lrz:latest" \
+  --where "url LIKE '%.de'" \
+  --limit 1000 \
+  --warc-config config.json
+```
+
+### Resume After Interruption
+
+```bash
+# Resume interrupted job
+owi query warc \
+  --remote "lrz:latest" \
+  --warc-config config.json \
+  --output ./warc-cache \
+  --resume \
+  --verbose
 ```
 
+## Performance Benchmarks
+
+Typical performance on modern hardware (32 cores, 64GB RAM, 10Gbps network):
+
+- **Throughput**: 300-500 records/second
+- **Bandwidth**: 50-100 MiB/s per datacenter
+- **Cache Hit Rate**: 90-95% for batch operations
+- **URL Fetch Time**: 50-100ms per batch (10-50 URLs)
+- **Background Refresh**: <10ms overhead per minute
