1.3. Topic Exchange A Topic exchange is similar to a Direct exchange, but uses keys that contain multiple words separated by a “.” delimiter. A message producer might create messages with routing keys like usa.news, usa.weather, europe.news, and europe.weather. Binding keys for a Topic exchanges can include wildcard characters: a “#” matches one or more words, a “*” matches a single word. Typical bindings use binding keys like #.news (all news items), usa.# (all items in the USA), or usa.weather (all USA weather items). |
Description of problem: Questions from beta customer: > 3. How does a wildcard work with the routing key? The documents you mentioned only talk about the "#" character. Does "a.#" match "a.b" and "a.b.c"? In some document (which I didn't note down), there was talk of "*" matching one word and "#" matching zero or more words. Is this true? Is there a list of wildcard examples some place? “*” matches a single word and ‘#’ matches zero or more words. This information should be included in the Tutorial for GA.
