_jaydeepkarale · x · 2026-09-05
Raul Junco of System Design Classroom outlines 5 event-driven patterns that go beyond chaining work queues: Copier (duplicating one stream for multiple outputs, e.g., rendering video in several formats), Process & Filter (trimming streams by criteria), Process & Split (splitting one stream into several queues), Sharder (sharding work to isolate failures), and Merger (consolidating multiple queues). Together they form a blueprint for scaling complex workflows with parallelism and fault isolation.
