TezzDB production data layer
Structured schema, migration, and query patterns for API services and system apps.
Data model contracts
- Schema versioning per service
- Forward-safe migration flow
- Deterministic model definitions
- Indexed query plans for hot paths
- Backup/restore and integrity checks
Service integration
Typical stack:
TezzServe middleware -> TezzApi routes -> TezzDB repository layer
Guidelines:
- Keep route handlers thin
- Centralize transactions in data service layer
- Emit structured error codes for API responses
Operational hardening
- Migration dry-run checks
- Query timeout and retry policy
- Data validation at API boundary
- Load-test with realistic datasets
- Backup verification in release drills
