Things are slightly complicated by the concept of exchange types. The amqp spec. defines the following four types:

The binding key must match the routing key exactly-No wildcard support.

Power query and power map are the new Excel-oriented functions released by Microsoft on the WPC recently. With these two features, self-help BI makes it easier for you to discover and process data and enrich the data visualization functions.
The predecessor of Power query and power map are data explorer and geoflow, both of which are mentioned in SQL Server 2014 ctp1. Combined with power intelligence and power view, these four functions form Microsoft's latest power Bi series.

Part 2: learning front-end things
The incomplete/inaccurate definitions of "frontend" and "backend" may be like this: "backend" in web development refers to the location where you store and organize website data. For example, a website like Yelp needs to store many things: its user and user's personal data, a large amount of restaurant information, which user has made a comment on a special restaurant, and so on.
Auckland, California, many musicians are wearing headphones and analyzing songs through computers. They are doing the most comprehensive analysis of music ever. This project is called "Music genetic engineering ". For each song, they will analyze hundreds of details, including the tone, rhythm, and lyrics. On the Pandora website, you only need to submit your favorite song or artist name to find the most similar song and play it like a broadcast station. This service is free of charge, mainly th

So, what is a Web framework? My understanding is this: there is a framework before people in deciding to make a new website, often need to add some of the same things to the new site every time. Since these are repetitive and tedious tasks, programmers have developed frameworks such as rails that move a lot of repetitive work beyond web develo

Recently, Facebook has unveiled its latest social search Graphael searches. Facebook's innovative approach has renewed confidence in the way people feel about their Facebook plagiarism and think it is no longer innovative. The launch of the Graphael search is of great importance to Facebook, whether it is in the area of social consolidation or expansion in search.
It has also been pointed out that Facebook is ambitious, not just to dominate the social sphere, but to fight Google's dominance in

Direct exchange allows us to selectively accept messages.However, this is still flawed.Although I can only require logs at the error and warning levels, I cannot further segment them.For example, I only want database-related error and warning-level logs.
To achieve this, we need to use another exchange type -- Topic.When the exchange type is topic, the routing key is a gr
routingKey = "error", the message will be routed to Queue1 (amqp. gen-S9b ..., This is the name of the Queue automatically generated by RabbitMQ) and Queue2 (amqp. gen-Agl ...); If we use routingKey = "info" or routingKey = "warning" to send messages, the messages will only be routed to Queue2. If we send messages with other routingkeys, the messages will not be routed to these two Queue.Topic
