Order Metadata Store (v0.0.1)
Long-term storage of order documents, receipts, and metadata files
The Order Metadata Store is an AWS S3 bucket that provides scalable, durable object storage for order-related documents and metadata. This storage system handles large files and documents that are associated with orders but don’t require real-time database access.
Overview
This S3-based object store serves as the primary repository for:
- Order confirmation PDFs and receipts
- Customer upload documents (delivery instructions, custom specifications)
- Order processing audit trails and logs
- Large metadata files that exceed database field limits
- Invoice documents and tax records
- Shipping labels and tracking documents

Integration Patterns
Write Operations
- Orders Service uploads receipts and confirmations
- Customer portal uploads delivery instructions
- Payment Service stores transaction receipts
- Shipping Service uploads tracking labels
Read Operations
- Customer Service retrieves order documents for support
- Reporting Service accesses historical data
- Compliance Service performs audit queries
- External systems via pre-signed URLs
Monitoring and Alerting
Key Metrics
- Upload Success Rate: > 99.9%
- Download Latency: < 100ms (95th percentile)
- Storage Utilization: Tracked per folder structure
- Cost Optimization: Storage class distribution
Alerts
- Upload failure rate > 0.1%
- Unusual access patterns (security)
- Storage cost increases > 20% month-over-month
- Lifecycle policy failures
Backup and Disaster Recovery
Backup Strategy
- Cross-Region Replication: Real-time to us-west-2
- Versioning: 30 previous versions retained
- MFA Delete: Required for permanent deletion
- Point-in-Time Recovery: Via object versioning
Disaster Recovery
- RTO: 2 hours (switch to backup region)
- RPO: < 15 minutes (replication lag)
- Testing: Monthly failover tests
- Documentation: Runbooks for recovery scenarios
