Go Realtime Channel Semantics for Logistics State You Actually Store
A realtime channel should carry a current logistics device event to authorized dashboard clients; it should not be treated as the system that remembers that event. The operational rule is blunt: commit durable device state to a database or log, publish a small notification that identifies the new state, and make every reconnect read from the durable source before resuming the live stream. Scope…
The article emphasizes the importance of distinguishing between realtime channel semantics and business state in logistics operations. It argues that a realtime channel should primarily serve as a delivery path for event notifications, rather than storing durable device state. The writer advocates for separating concerns by committing durable device state to a database or log, while the realtime channel only transmits small notifications identifying the new state.
It stresses that the channel should not be treated as a database or a source of complete historical records. The article also highlights the need to set separate SLOs for durable ingestion and dashboard freshness, and to test the gap between them. Ultimately, the writer concludes that only the business state of where a device unit last reported and whether that observation supersedes an earlier one should be stored in the authoritative store, while transport, membership, and delivery state remain implementation details.
