# Database Layer Hardening Plan
|
|
|
|
## Goal
|
|
Ensure database access patterns are efficient, resilient, and match schema constraints across `pkg/database` and integrations.
|
|
|
|
## Tasks
|
|
|
|
1. **Schema & Migrations**
|
|
- [ ] Review current schema/migrations (if any) to confirm tables/indexes align with access patterns.
|
|
- [ ] Document schema in `docs/` (ER diagram, migration history).
|
|
|
|
2. **Connection Management**
|
|
- [ ] Validate pool settings (`max_open`, `max_idle`, `conn max lifetime`) and expose via config.
|
|
- [ ] Implement health checks and failover for primary/replica setups.
|
|
|
|
3. **Transaction Integrity**
|
|
- [ ] Ensure critical writes use transactions with rollback on error.
|
|
- [ ] Add tests for idempotent persistence (e.g., duplicate opportunities).
|
|
|
|
4. **Performance & Monitoring**
|
|
- [ ] Instrument slow query logging and Prometheus metrics.
|
|
- [ ] Run load tests to ensure queue/execution writes keep up under peak load.
|
|
|
|
5. **Docs & Runbooks**
|
|
- [ ] Update deployment docs with connection strings, maintenance tasks, backup/restore procedures.
