Backpressure Handling & Flow Control

A feedback mechanism where a slow consumer signals an upstream fast producer to throttle its emission rate, preventing consumer memory buffer exhaustion.

STAFF ENGINEER TAKEAWAY: Without backpressure, fast producers will overflow consumer RAM buffers, triggering Out-Of-Memory (OOM) crashes.

📬Message Queues (PTP Asynchronous Buffering)

Point-to-point asynchronous buffers where producer services enqueue jobs, and competing consumer workers process tasks at their own decoupled pace.

📢Publish/Subscribe Event Streaming

Publishers broadcast events to topics without knowing who the subscribers are. Multiple independent consumer groups read from the same topic simultaneously.

⚡Event-Driven Architecture (EDA)

Systems coordinate state changes through state-change notifications and events rather than synchronous request/reply HTTP/RPC calls.

📐Domain-Driven Design (DDD) & Bounded Contexts

Divides large software domains into discrete logical boundaries where ubiquitous language and domain models are strictly defined and isolated.
