System Design
5 notes
System Design: Delivery Semantics, Rollout, and Operations
Complete the production loop with stable decision IDs, idempotent effects, reproducible replay, shadow/canary rollout, SLO burn, and failure drills.
System Design: Hot Path, Partitioning, State, and Backpressure
Use dispatch indexes, shared computation, keyed state, and lane-aware backpressure to keep per-event rule-evaluation cost predictable.
System Design: Requirements, SLOs, and Capacity Assumptions
Turn “evaluate events against rules” into testable contracts, then size and recover the system with explicitly isolated interview assumptions.
System Design: Rule Compilation and the Control Plane
Treat rules as executable production behavior, from DSL and IR through static checks, immutable bundles, progressive activation, and rollback.
System Design Series: High-Throughput Rule Engine Overview
Connect the control, data, and evidence planes through an explainable, releasable, and replayable system contract.
