Implement the circuit breaker pattern to prevent cascade failures in distributed systems. Use when adding resilience to API clients, external service calls, or any operation that can fail and should fail fast.
Hierarchical exception system with HTTP status codes, machine-readable error codes, and structured responses for consistent API error handling across all endpoints.
Implement robust background job processing with dead letter queues, retries, and state machines. Use when building async workflows, scheduled tasks, or any work that shouldn't block the request/response cycle.
Implement cursor-based and offset pagination for APIs. Covers efficient database queries, stable sorting, and pagination metadata.
Implement idempotent API operations to safely handle retries and prevent duplicate processing. Use when building payment APIs, order systems, or any operation that must not be executed twice.
Implement Server-Sent Events (SSE) for real-time updates with automatic reconnection and heartbeats. Use when building live dashboards, notifications, progress indicators, or any feature needing server-to-client push.
Redis-backed SSE stream management with stream registry, heartbeat monitoring, completion store for terminal events, and automatic orphan cleanup via background guardian process.
Multi-layer caching with type-specific TTLs, get-or-generate pattern, memory and database layers, and graceful invalidation without cache stampede.
Implement health check endpoints for load balancers, Kubernetes, and monitoring. Covers liveness, readiness, and dependency checks.
Implement multi-tenant architecture with tenant isolation, data separation, and per-tenant configuration. Supports shared database and schema-per-tenant models.
Two-phase commit matchmaking that verifies both player connections before creating a match. Handles disconnections gracefully with automatic re-queue of healthy players.
Implement multi-layer caching with Redis, in-memory, and HTTP caching. Covers cache invalidation, stampede prevention, and cache-aside patterns.
