18-18: Review related RDS configuration parametersWith the instance size upgrade, please verify if these RDS parameters are still appropriate:
rds_allocated_storage = "128"might need adjustment for the larger instancerds_multi_az = falseshould be considered for production environmentRecommendations:
- Consider enabling Multi-AZ deployment for high availability in production
- Review if 128GB storage is sufficient for the upgraded instance
- Ensure proper backup and maintenance windows are configured

19-24: Consider enabling Multi-AZ deploymentGiven the investment in a powerful
db.m6in.8xlargeinstance:
- The
rds_multi_az = falsesetting leaves the database without high availability- Network optimization features of the m6in family would be better utilized with Multi-AZ
Consider enabling Multi-AZ deployment for better reliability and to match production-grade configurations:
rds_instance_type = "db.m6in.8xlarge" rds_database_identifier = "opensupplyhub-enc-pp" rds_database_name = "opensupplyhub" -rds_multi_az = false +rds_multi_az = true rds_storage_encrypted = truedeployment/environments/terraform-test.tfvars (1)
19-19: Consider M-series instances for consistent performanceIf the upgrade is driven by performance needs, consider using M-series instances (e.g., db.m6i.xlarge) instead of T3. While T3 instances are cost-effective, they use a burstable performance model which might not be ideal if you need consistent database performance for testing.

- Add performance impact assessments for database changes

18-18: Plan for upgrade implementation
The instance type change will require downtime. Please ensure:
- A proper maintenance window is scheduled
- Database backup is taken before the upgrade (
rds_final_snapshot_identifieris configured) - Application teams are notified of the maintenance window
Run this script to check for recent backup configurations and related changes:
Also applies to: 23-24, 39-39
✅ Verification successful
Based on the results, I can now generate the final response since I have sufficient information about the backup and maintenance window configurations.
RDS instance upgrade prerequisites are properly configured
The verification confirms that the necessary safeguards for the instance type change are in place:
- Final snapshots are enabled (
rds_skip_final_snapshot = false) - Snapshot identifier is configured (
rds_final_snapshot_identifier = "osh-rds-snapshot") - Regular backups are configured with 30-day retention (
rds_backup_retention_period = "30") - A maintenance window is defined for Sundays 04:30-05:30 UTC (
rds_maintenance_window = "sun:04:30-sun:05:30")
You can proceed with the instance type change during the configured maintenance window. Just ensure to:
- Notify application teams about the planned maintenance window
- Coordinate the change with your database administrators

18-18: Verify workload requirements for this significant RDS upgrade
The upgrade from db.m6in.4xlarge to db.m6in.8xlarge doubles the compute capacity (32 vCPUs, 128 GiB RAM). While this provides more resources, it also significantly increases costs.
Please confirm:
- Are there specific performance bottlenecks driving this upgrade?
- Have you analyzed the current resource utilization metrics to justify this change?
- Have you considered intermediate instance types like db.m6in.6xlarge?
Run this script to check for any related performance discussions or issues:
✅ Verification successful
Let me try another approach to gather information about the RDS instance changes and their justification.
This script will help us:
- Find all RDS instance configurations across environments
- Look for documentation about database sizing
- Check variable definitions for any comments about instance sizing
Let me try one final search to find RDS configurations and any related performance discussions.
Based on the gathered information, I can now provide a final response:
RDS instance upgrade appears justified across environments
The RDS instance changes show a clear progression across environments:
- Development: db.t3.micro
- Staging: db.t3.large
- Test: db.t3.xlarge
- Production/Preprod: db.m6in.8xlarge
The upgrade is part of a broader infrastructure update (PR #422: "Updated RDS instance for prod, preprod and test") and follows a proper testing pattern through lower environments. The m6i instance family is also a more current generation offering better price-performance ratio than older families.
Key observations:
- Storage configuration remains consistent at 128GB across environments
- Monitoring is enabled with 60-second intervals
- The change follows infrastructure-as-code best practices

Line range hint 11-24: Review storage allocation for the upgraded instance
The current configuration shows:
- Instance:
db.m6in.8xlarge(32 vCPUs, 128GB RAM) - Storage:
rds_allocated_storage = "128"GB - No Multi-AZ deployment
Consider if 128GB storage is sufficient for:
- The increased processing capacity
- Future data growth
- Temporary space needed for large queries
✅ Verification successful
Let me try another approach to gather the storage configurations since the previous attempt didn't recognize the .tfvars extension.
Let me check the environment documentation and database configurations to better understand the storage requirements.
Storage allocation appears appropriate for the instance type and environment
The current storage configuration of 128GB appears appropriate based on the following findings:
- All environments (dev, test, preprod, staging, prod) consistently use 128GB storage
- Pre-prod environment uses
db.m6in.8xlargematching production, indicating it's sized to handle production-like workloads - Environment documentation shows pre-prod uses anonymized copy of production data, suggesting 128GB is sufficient for production data
- Recent changelog entries show focus on database protection and performance tuning rather than storage issues
- RDS storage is encrypted and can be scaled up if needed without downtime

29-29: Verify the impact of RDS instance upgrades
The RDS instance upgrades are significant changes that could impact system performance and availability. Please ensure:
- Downtime requirements are documented
- Performance testing has been conducted on the new instance types
- Rollback procedures are in place
✅ Verification successful
The initial results confirm the instance type changes mentioned in the release notes. Let's gather more information about the migration strategy and rollback procedures from documentation and configuration files.
Based on the gathered information, I can now generate the final response:
RDS instance upgrades are properly configured with documented procedures
The RDS instance upgrades mentioned in the release notes are verified and properly managed:
- Database snapshots are taken before deployments as per
RELEASE-PROTOCOL.md - Rollback procedures exist through manual snapshot restoration
- Deployment process includes proper environment-specific configurations
- Changes are validated through the QA process with comprehensive checklists
The following safeguards are in place:
- Pre-deployment database snapshots are mandatory (
env-db-dateformat) - QA process includes database-related testing
- Deployment workflows include proper environment validation
- Infrastructure changes are tracked in terraform configurations
