Questions:When we put all the supervision tree in a project through a simple function game:start (), we find that the tree structure is particularly complex, with only one root node, and then it expands.Here, this is why application appears, designing a sub-block (application) that can be switched on at any time. For example: In the Log app, DB app, game app, connect app.So the switch management of these applications is very convenient, "Imagine if you use supervisor, the runtime also to manuall

Matching: Eg: F = {A, XX, 123 }, {A, XX, YY} = f. % the value of YY is 123. 2. Erlang: element (Pos, mytuple). Pos indicates the first element, starting from

The main problem with map matching is to recall the map group map in Erlang, which is called hash hash or Dict dictionary in other languages. Erlang supports mapping groups starting with the R17 version Create a mapping group The mapping group in Erlang is represented by a struct #{} that creates a mapping group that can be Copy Code code as follows:
ExchangeThe previous log System example broadcasts all messages to all consumers. We want to extend it so that it allows filtering information.With fanout type of exchange, there won't be much flexibility, just broadcasting.With direct-type exchange, direct Exchange's algorithm is simple, and messages with the routing key and the same binding key for the queue are delivered to the queue. See:This setting, we can see that there are two queues bound to a direct type of exchange. Q1 's binding key
