A robust, scalable multi-tenant SaaS application backend built with Rust, featuring high-performance networking, reliable data isolation, and a modern developer experience.
| Concept | Location | Purpose |
|---|---|---|
| RLS (Row-Level Security) | All tables | Tenant Isolation: Ensures Company A can never access Company B's data at the database level. |
| Optimistic Locking | PUT /tasks |
Concurrency Protection: Detects and prevents data loss if two users edit the same task simultaneously. |
| Full-text Search | GET /tasks?search= |
Efficient Discovery: Allows users to search task titles and descriptions with advanced relevance. |
| GIN Index | tasks.search_vector |
Search Optimization: Makes complex full-text search queries extremely fast. |
| JSONB + GIN | tasks.metadata |
Dynamic Schemas: Supports flexible custom fields per-tenant without modifying the global schema. |
| Recursive CTE | GET /tasks/:id/subtasks |
Hierarchical Data: Fetches an entire tree of nested subtasks in a single efficient query. |
| SKIP LOCKED | Job Worker | Parallel Execution: Allows multiple workers to safely process jobs concurrently without double-claiming. |
| Redis Cache-Aside | GET /projects |
Performance: Reduces database load for frequently accessed, rarely changing data. |
| Redis Pub/Sub | WebSocket Updates | Real-time Sync: Broadcasts task updates and alerts to all connected users instantly. |
| SQLx Migrations | Schema Management | Consistency: Ensures version-controlled, reproducible schema updates across all environments. |
