Routing & pub-sub
Worked examples of fan-out and content-based routing over a single published message.
These tutorials show publish-subscribe and routing in practice: one order serving many departments, region-based routing with a dead-letter branch, one canonical order from two channels, and debatching a settlement file.
Order fan-out. One published Order, three independent subscriptions: warehouse, finance, account manager.
Regional order routing. A promoted Region drives one filtered subscription per endpoint, with a dead-letter branch.
Two channels, one order. JSON and SFTP CSV both mapped to one canonical Order, so downstream ports are built once.
Settlement file debatch. One nightly file split into individual transactions, each marked paid by a SQL Caller.
