EasyDB Best Practices: Design, Security, and Performance
1. Design
- Schema simplicity: Model only necessary fields; prefer denormalized documents for read-heavy workloads and normalized relations for complex transactions.
- Naming conventions: Use consistent, descriptive names for tables/collections and fields (e.g., snake_case or camelCase).
- Versioning: Store a schema_version field and migrate incrementally; make migrations idempotent.
- Indexing strategy: Index fields used in filters and sorts; avoid excessive indexes that slow writes.
- Pagination: Use cursor-based pagination for large result sets to avoid offset performance issues.
- Caching layer: Cache frequent read queries (e.g., Redis) and cache invalidation patterns that align with update operations.
2. Security
- Authentication & Authorization: Enforce strong auth (OAuth2/JWT) and implement role-based access control (RBAC) or attribute-based access control (ABAC).
- Least privilege: Grant minimum permissions needed for services and users.
- Encryption: Use TLS for in-transit encryption and AES-256 (or equivalent) for at-rest encryption of sensitive fields.
- Input validation & sanitization: Validate and sanitize all inputs to prevent injection attacks; use parameterized queries/prepared statements.
- Audit logging: Record who changed what and when; protect logs from tampering and rotate them securely.
- Secrets management: Store DB credentials and keys in a secret manager (HashiCorp Vault, AWS Secrets Manager).
- Backups & recovery: Regular automated backups, encrypted storage, and tested restore procedures; keep multiple retention points.
3. Performance
- Query optimization: Profile slow queries, add targeted indexes, and rewrite inefficient queries (avoid SELECT).
- Connection pooling: Use connection pools to limit resource overhead and reuse connections.
- Batching & bulk operations: Group writes/reads where possible to reduce round trips.
- Asynchronous processing: Offload heavy work to background jobs (queues, workers) to keep foreground latency low.
- Sharding & partitioning: Horizontally partition large datasets by stable keys to distribute load.
- Monitoring & alerts: Track latency, throughput, error rates, resource utilization; set alerts for anomalies.
- Resource sizing & autoscaling: Right-size instances and enable autoscaling based on real metrics.
4. Operational Practices
- CI/CD for schema changes: Apply schema and migration changes via CI with rollback capability.
- Chaos testing: Periodically test failure modes (network, node restarts) to validate resilience.
- Documentation: Maintain runbooks for deployment, backup restore, and incident response.
- Cost monitoring: Track storage, I/O, and egress costs; optimize indices and retention to reduce expenses.
5. Quick checklist (for immediate action)
- Add TLS and enable encryption at rest.
- Implement RBAC and rotate secrets.
- Create targeted indexes for slow queries.
- Set up automated encrypted backups and test restores.
- Instrument monitoring and alerts for key metrics.
